<p>An industrial manufacturer has introduced an advanced utility-scale inverter in its new Series 6001 energy storage grid-connect inverter, engineered to provide improved power stability for wind and solar energy customers. Engineered by Eaton Corp. for utility-scale grid-connect battery applications, the Series 6001 inverter lets customers achieve full battery storage potential because of a large direct current operating voltage window. Eaton power electronics switching techniques result in lower losses and improved efficiency. The Series features proprietary electronics that make it one of the most efficient inverters in the renewable power market.</p>
<p>“With the recent IE Power acquisition, Eaton now combines strong design capabilities with an established product to deliver dependable and efficient inverters for utility-scale customers,” Chris Thompson, business unit manager at Eaton.</p>
<p>The Series 6001 provides high-performance conversion in utility applications for wind, solar and other heavy industrial power applications by creating a high-performance link between the power source and battery. The Series 6001 helps utilities reduce downtime and clear faults faster by staying on line during fault conditions. Low-voltage ride through (LVRT) with proprietary algorithms let the Series 6001 inverter run near zero line voltage for extended periods, while maintaining line synchronization. Also, high-voltage ride through (HVRT) capability is achieved through conservatively rated components.</p>
<p>Ride-through capabilities meet the requirements of North American and European standards: Federal Energy Regulatory Commission (FERC), Bundesverband der Energie und Wasserwirtschaft (BDEW), and E-ION. These standard compliance settings are field selectable to match site requirements.</p>
<p>A four-quadrant inverter for battery charge and discharge, the Series 6001 withstands demanding applications with a rugged design. The enclosure meets a seismic zone 4 rating and is available as indoor or outdoor rated. The dust-tight section protects the liquid-cooled inverter and electronics control components from harsh and dusty environments. Also, a vented section houses robust air-cooled magnetics.</p>
<p>The Series 6001 is rated for 500 kilowatt (kW), 1,000 kW and 1,500 kW applications. Designed for a 20-year life for utility applications, the unit has conservatively rated magnetics, liquid-cooled power modules with over seven million hours mean time between failure (MTBF) and a rugged enclosure for demanding environments. Additionally, the transformerless design, proprietary control strategies and filter design result in over 98% peak power efficiency.</p>
<p>&nbsp;</p>
<p>Eaton grid-connect inverters provide the required grid support, including: low, zero and high voltage ride through; standalone/black start operation; islanding detection; utility communication; and full four quadrant operation.</p>
<p>In conjunction with a system supervisory controller and feedback from the point of common coupling (PCC), additional grid support features can be achieved. These include: peak power shaving, load leveling, grid frequency regulation and voltage control.</p>
<p>The configurable Series 6001 interface allows communications and control of the inverter through a variety of links. By connecting to a system supervisory controller, transmission providers are able to send commands and receive data.</p>

<p><span style="font-size: small;"><span style="font-family: Arial;"> The public-private partnership will develop innovations that will enhance the capabilities and performance of advanced wind systems in tapping the vast potential of this renewable energy resource and ultimately bring the nation closer to 20% wind energy by 2030.</span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;"> Gamesa and NREL will collaborate on work in these key areas by developing new wind turbine components and rotors for the U.S. market, researching and testing the performance of new control strategies, and devising models that will help advance the development of offshore wind in U.S. waters.</span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;"> “Wind energy is going to continue to play a key role in creating a stronger and more sustainable American economy,” said Dr. Miguel Angel Gonzalez-Posada, Vice President of Technology for Gamesa North America. Gamesa has installed and commissioned a G97 Class IIIA 2.0 MW test wind turbine at NREL’s National Wind Technology Center near Boulder, Colorado. </span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;">“These types of collaborations demonstrate a commitment to crucial technology development and the public-private partnerships necessary to ensure continued momentum of the wind-power industry,” says NREL’s Deputy Laboratory Director for Science and Technology Dana Christensen. “Our role with the Department of Energy is to reduce technical risks and thereby help accelerate next generation technology into the marketplace. NREL is proud to be at the forefront of this important work.”</span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;"> Since its introduction last year, Gamesa’s G9X-2.0 MW turbine platform has gained recognition for its blade design, updated nacelle, enhanced control systems, and other features that substantially increase energy output. The G97 Class IIIA 2.0 MW model, which will serve as the test platform with NREL, is intended for low-wind sites, a segment from which Gamesa expects over half of all future on-shore demand.</span></span></p>
<p><span style="font-family: Arial; font-size: small;"> Gamesa and NREL also will work to design and test new lightning protection and other turbine </span><a href="http://www.windpowerengineering.com/maintenance/condition-monitoring-maintenance/condition-monitoring-101/"><span style="font-family: Arial; font-size: small;">conditioning systems</span></a><span style="font-size: small;"><span style="font-family: Arial;">, examining their performances in a range of temperatures at high altitude to ensure that they function in us environments. New converters will be used to test ways to increase energy output while enhancing component reliability. Extensive tests also will be conducted on other turbine key components, examining motion, temperatures, stresses and vibration levels, where the findings could lead to improvements that enhance the reliability of future us installations.</span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;"> <strong>Control strategies: </strong>The two organizations<strong> </strong>also will work to develop new control strategies that improve energy capture while decreasing loads, which will be accomplished through development of new algorithms. New control strategies will be tested throughout the turbine. Testing will include measurement of aerodynamic loads, the response of blade profiles, and pitch actuation. Output will be measured to determine how changes affect power output and its fluctuations, and what the effects are on structural loads and the drive-train response.</span></span></p>
<p><span style="font-family: Arial; font-size: small;"> <strong>Offshore wind: </strong>NREL and Gamesa will conduct a round-robin exercise using existing turbine modeling software to develop new methods that will let companies predict the behavior of </span><a href="http://www.windpowerengineering.com/construction/projects/offshore-wind/"><span style="font-family: Arial; font-size: small;">offshore wind turbines</span></a><span style="font-size: small;"><span style="font-family: Arial;">, as well as the potential sensitivity of equipment to the offshore environment. The two organizations will examine factors such as wind-speed distribution, turbulence intensity and wind shear, waves, tides, currents, temperature, lightning and ice formation, and how these factors correlate with performance and the potential cost for the design, operation and maintenance of offshore wind systems.</span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;"> “This research project will examine every aspect of the turbine, from its base to the blade tip at its apex, along with all the parts that make it turn,” said Gonzalez-Posada. Full project testing on the entire slate of programs began January 2012. The core provisions of the public-private partnership run through 2013, with options for two additional years of collaboration.</span></span></p>

<p>Voltage regulation and volt ampere reactive (VAR) compensation wield the most influence over the efficiency of a power distribution system, according to Sergio Arellano, product line manager with Thomas &amp; Betts. “The fastest way to improve the efficiency of <a href="../../../../../design/electrical/grid/electricity-distribution-101/">power distribution</a> is to install switched capacitor banks with smart electronic controls. It also provides the quickest return of investment of all possible methods.”</p>
<p>Among the new capacitor bank controls offered by this collaboration is the SEL-734B Three-Phase Monitor and Capacitor Bank Control, which is used to automate and monitor three-phase banks, combined with T&amp;B’s selection of VerSaVac (VSV) one and three-phase vacuum switches for pole-top capacitors, and VBM distribution vacuum switches. Capacitor bank upgrade kits are also available for applying the capacitor bank control system to existing fixed-capacitor banks.</p>
<p>The new capacitor-bank control includes a power-quality monitoring, control, and reporting functions, and can be combined with metering accuracy measurements. Its plug-and-play pole mount enclosure provides weather-protected space to mount network radios, power supplies and encrypting transceivers. The capacitor-bank controls also include SEL standard software tools, a 10-year product warranty on SEL products, and technical support.</p>

<p><span style="font-size: small;"><span style="font-family: Arial;">A full-power converter design by The Switch features fault ride-through (FRT) capability for better grid-side performance. The new converters match the most stringent grid code in the world to date, the German BDEW 2008 directive. They also comply with E.ON 2006, Transmission Code 2007 and Chinese grid code 2008. During faults, the converter stays connected to and supports the grid – even with zero-voltage ride-through capability. This results in future-proof grid compliance. The built-in FRT capability also creates a cost advantage. Even the smallest turbines on wind farms are being retrofitted with additional FRT upgrade kits that cost as much as new, complete converters by The Switch. </span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;">The new converter design is ideal for offshore installations, because the cabinet has been improved to minimize the impact of environmental influences in harsh ocean conditions. The upgrades include a more rugged enclosure and better sealing. In addition, the converter includes a built-in humidity control that removes humidity from inside the cabinet, making it highly reliable. The new converter, designed to match all turbine applications ranging from 1 to 6 MW, also reduces cabinet size by up to 30%. The length of The Switch 2 MW cabinet is now only 2.4 meters, which makes the placement of the converter easier in the nacelle or the tower. Higher power density is the design criteria also in higher power ranges. </span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;">“In China, the importance of FRT capability has been recognized only recently as a result of large power outages, and the slowdown in the market is closely linked to these quality issues. The new products exceed the maximum grid performance requirements in China,” says Jukka-Pekka Mäkinen, President and CEO. Sales of the new converter series will start early in 2012. </span></span></p>

<p>Chinese manufacturer Dongfang Steam Turbine Works (DSTW) was working on a wind farm project of 66, 1.5-MW turbines and had to establish a SCADA system to remotely monitor on-site equipment and operations while recording operation data for real-time analysis. To make matters worse, Northeast China’s harsh weather called for rugged and reliable networking devices.<br />
The company also decided the system needed network redundancy with a fast recovery for system reliability, and at least three fiber-optic ports for uplink and long distance outbound transmissions. In addition, network-management software had to monitor and manage the system without undue complexity.</p>
<p>After sufficient evaluation, the Chinese engineers selected MOXA/s rack mount managed industrial Ethernet switches an excellent fit for their network infrastructure requirements.</p>
<p>Moxa engineers suggested installing one industrial Ethernet switch (EDS-208A-M-SC) atop each wind turbine to connect to the equipment inside the turbine. This switch connects to another switch (EDS-408A-2S1M-ST-T) at the bottom of the turbine by a fiber optic port. The switch comes with three fiber optic ports, one of which is the uplink connection to the EDS-208A and the other two connect to adjacent wind turbines.<br />
Due to high security and availability requirements, the company used a ring topology in the wind-farm network for fast redundancy in case of network failure. The control center uses Moxa’s rackmount managed industrial Ethernet switches (IKS-6726) to connect field switches with the SCADA system and network management servers. MXview 1.0 network management software then helps operators monitor network status by automatically discovering the network topology and displaying real-time alarm information. The software supports SNMP V1, V2c, and V3, and presents historical traffic statistics and event logs for troubleshooting. The equipment is rated for -40 to 75°C.</p>

<p><span style="font-size: small;"><span style="font-family: Arial;">An uninterruptable power supply or UPS may be a best way to provide stable power to a company network. Current UPS designs store energy in batteries in dc mode. When necessary, the device supplies power in ac mode, thanks to a dc-to-ac converter. It works in switch-mode and so generates electromagnetic noise, conducted and radiated, which affects its operation and nearby electronic devices. This electromagnetic emission has to meet limits established by applicable standards, and the environment in which it is supposed to work. Typical standard are EMC IEC 62040-2 and EN 50091-2.</span></span></p>
<p><span style="font-size: small;"><span style="font-family: Arial;">One EMC test, for conducted emissions, measures noise in the power using a LISN. The measurement frequency is 150 kHz to 30 MHz and the maximum limit allowed depends on the applicable standard and the environment where the unit will work, domestic or industrial.</span></span></p>
<p><span style="font-family: Arial; font-size: small;">To overcome these conducted emission tests, Premo Group offers a wide range of EMC filters for UPS, with various ranges of current, voltage and filter stages, built according to UL1283 and EN60939-2 standards. The company offers a new PFT series, a three-phase UPS with neutral filter for three-phase power delivery without transformer. This PFT Series offers currents from 3 to 150A and working voltage to 520 Vac, 50 or 60 Hz, providing high common mode attenuation and differential, as well as low-leakage current. This family of filters offers a compact design and is available in different versions, with fast-on connection, screws, or terminal blocks. The filters have been developed to fulfill the specific needs of this application in terms of attenuation levels, volume, weight, and connections. Premo continuously improves its EMC filter designs, in collaboration with development centers, universities, suppliers and customers, innovating new technologies such as IPEM and introducing new magnetic materials (nanomaterials, and new alloys) for optimum results in operation mode, reliability, size and efficiency. Premo EMC has fixed an on-site laboratory to carry out the EMC tests in machines or installations of its customers. Solutions are suggested to fulfill a specific EMC standard.
