贵州电网RTDS仿真试验建模研究

为了开展广域PSS控制器功能与性能测试试验,搭建了贵州电网2012年丰大运行方式RTDS模型,通过稳态潮流和故障暂态情况下RTDS与BPA等效系统仿真结果的对比,证明了所建立的RTDS模型可以满足电网实时仿真和设备性能测试的相关要求,并与其他外部装置共同构成一个闭环测试系统,对广域PSS的基本控制功能进行了仿真试验研究,验证了在发电机PSS运行情况下投入广域PSS控制器能进一步增加系统阻尼,可有效抑制电网区域间振荡,这为该控制系统应用于实际工程提供了有力的技术支持。

Research on RTDS-based Modeling and Simulation Testing of Guizhou Power Grid

In order to test the function and performance of wide-area PSS controller, the RTDS model of Guizhou Power Grid is set up according to the peak load scenario. Steady power flow and fault transient process with the RTDS and BPA equivalent system are simulated and compared, and it is proved that the RTDS model can meet the relevant requirements of real-time simulation and equipment performance testing. A closed-loop test system is constituted with other external devices. A simulation testing is conducted on the basic control functions of the wide-area PSS, and it is verified that the wide-area PSS can further increase the system damping in operation of the generator PSS, effectively suppress the inter-grid oscillation, and provide a strong technical support for the pratical application of this control system.
