摘要: Wind farms are becoming important distributed renewable energy resources. However, voltage stability issues with wind employing fixed-speed induction generators may require such systems to be augmented dynamic compensation devices, as STATCOM units. In preparation for deployment of a 10 MVA at an existing farm in the Bonneville Power Administration (BPA) system, controller is tested through hardware-in-the-loop simulation real-time digital simulator, which will model both BPA system and high fidelity, transient models. This paper presents groundwork conducted testing controller, including studies improvement facilitated by introduction into system. The enhancement generator studied analytically power-voltage torque-slip relationships simple power well used controller. Simulation results from approaches compared illustrate potential benefit preventing collapse caused serious network changes, opening line, Fault Ride Through capability
