1 GE Energy Operability, performance, and availability

2 Operability: Proven Technology Experience power generation similar to a conventional power plant with GE s 600 kilowatt (kw) Solar Inverter, enabled with grid-friendly features and backed by GE s history of innovation in power electronics. GE Energy s is our latest evolution in renewable energy power electronics. Building on GE s leadership in the renewable energy industry and designed with the heritage of GE s proven controls expertise, the provides the superior grid performance and operational flexibility necessary for available, reliable solar electric power. Technical Specifications GE s Renewable Power Electronics Expertise 12,000+ power electronics packages in operation worldwide* 19 countries 170+ million operation hours 100,000+ GWh produced * Based on global wind turbine installed base Output Power Nominal AC Power 600 kwac Nominal AC Voltage 480 Vac (+/- 10%) Nominal AC Line Current 810 Aac Nominal Grid Frequency 60 Hz Nominal Power Factor 0.99 or greater Power Factor Operational Range +/- 0.9 Line Distortion Per IEEE519 Efficiency Peak Conversion Efficiency > 97.0% CEC Weighted Efficiency > 96.5% Night Time Consumption < 250 W Input Power Input Voltage Max 600 Vdc MPPT Voltage Range Vdc MPP DC Current 2,080 Adc Max Isc 2,400 Adc Dimensions Height 2,350 mm Width 3,500 mm Depth 1,300 mm Weight 3,175 kg Environmental Design Outdoor Enclosure NEMA 3R (NEMA 3S Bridge and Controls) Operating Temperature to 50.0 C Note: Efficiency measured using the CEC Weighted Average, and does not include losses of the Medium Voltage Transformer. GE s is the fundamental power block within a system and can be grouped to support the size and scope of your solar electric power plant. To ensure ease of permitting, installation, and inspection, the GE inverter is certified to applicable UL and CSA standards. Inverter Grid Features GE s innovative SolarRIDE-THRU technology allows inverters to stay on-line during grid disturbances. SolarRIDE-THRU includes Low Voltage Ride Through (LVRT), Zero Voltage Ride Through (ZVRT), and High Voltage Ride Through (HVRT) capabilities. This broad range of capability provides uninterrupted service in the face of grid disturbances, which are prevalent in utility grids around the world. GE s SolarFREE Reactive Power feature provides controlled reactive power through all operating conditions. Even when not generating active power, inverters with SolarFREE can provide reactive power for continuous voltage support and regulation. This feature can eliminate the need for grid reinforcements even in no-sun conditions and may allow for more economic commitment of other generating resources. Data Visualization A convenient web-based Human Machine Interface (HMI) is provided for local or remote operation of each inverter. This enables password-protected access to inverter operation functions including startup, shutdown, mode selection and set-point adjustments, as well as alarm and maintenance. The HMI also provide data collection and display capability including: Voltage at Point of Interconnection (Percent) SolarRIDE-THRU High Voltage Ride Through Low Voltage Ride Through Zero Voltage Ride Through Time (Seconds) Live data trends Alarm and event messages Control status indication I/O data for options such as string current, temperature, and irradiance monitoring The GE inverter utilizes a two-stage power conversion approach, which provides the output of the inverter at a standardized grid voltage of 480 Vac. This voltage minimizes AC side current, eliminating the need for an intermediate transformer, resulting in higher conversion efficiency compared to a single-stage power conversion system. If multiple converters are connected to a medium voltage grid, a standard medium voltage transformer can be used. Fitted with a robust outdoor-rated enclosure, the GE has been designed to perform even in extreme environmental conditions.

3 Performance: Maximizing Plant Operations GE s comes enabled with SunIQ* a reliable plant level control platform that includes the modern networks, software tools, and diagnostics needed to increase system availability. Solar Monitoring and Controls GE can take your solar plant s performance to the next level with our SunIQ system, helping you to get the most complete information and desired production from your plant. SunIQ is an integrated plant level monitoring and control platform designed to bring together real-time plant-wide data visualization, data analysis, and troubleshooting with plant level operational control to enhance grid integration of solar. SolarSCADA Features Real-time data visualization of the plant with drill down capability Reporting based on historical data in SQL database Alarm notification via /sms User configurable dashboards Remote troubleshooting of plant assets Industry standard interfaces for data access SolarFREE: Reactive power even in no-sun conditions SolarRIDE-THRU: Uninterrupted inverter operation through grid disturbances 600 kw Solar Inverter 600 kw Solar Inverter Plant Control The SunIQ system includes a plant level controller that coordinates behavior of multiple inverters, thus enhancing the grid integration capabilities of the Solar power plant. Like a conventional power plant, the system controls reactive power supply (KVAR) to the grid, regulating system voltage and stabilizing weak grids. The system is also capable of regulating active power (kw) providing the grid operator with the ability to curtail kw output as well as control frequency droop and ramp rate. The system can be accessed either locally or remotely via the plant monitoring system or alternatively through analog/digital I/O. GE s system provides the following capabilities similar to those of a conventional power plant: Communication Network Local Clients Voltage/PF control: Regulates VARs, reduces voltage variations at point of interconnect (POI) Power curtailment: Regulates active power at the POI Over frequency droop: Reduces active power in response to frequency increase Ramp rate control: Controls MW/sec of generation change Start-up/shut-down: Avoids addition or removal of large blocks of power into/out of the grid at once CT/PT Signals Firewall Point of Grid Interconnect ODBC/OPC GE Remote Monitoring Grid Operator SunIQ Grid-friendly plant controls operate like a conventional power plant Remote Clients Control and Monitoring System SMS Enterprise System Advanced operational tools understand and optimize system performance Power (kw) Passing Clouds Voltage (kv) Passing Clouds With the GE System, voltage at the POI is regulated tightly. Without the GE System, changes in irradiance leads to voltage fluctuations. Time Time Plant Monitoring GE s Solar SCADA application is included in the SunIQ system and provides a broad set of intuitive tools for a secure, real-time view of a solar plant s operation and maintenance. The web-based SCADA application allows for evaluation of plant performance using real-time and historical data to diagnose performance variation sooner and allow for rapid fault resolution. In addition, the application provides a range of supervisory control functions for the inverter allowing operators to remotely command plant setpoints. By integrating our monitoring and control system into your solar power plant, you can meet many emerging grid code requirements related to a solar plant s response.
