摘要
基于电力系统分析软件包PSASP,使用其用户自定义功能,建立了辅助频率控制模型。该模型为青藏直流联网工程用户自定义高压直流输电模型的一部分。通过在2011年青海与西藏联网数据中应用,仿真验证了辅助频率控制用户自定义模型对于改善整流侧及逆变侧交流系统的频率、提高交直流系统的安全稳定性的正确性及必要性。
A detailed user--defined (UD) auxiliary frequency controller (AFC) model of HVDC has been developed based on Power System Analysis Software Package (PSASP. The UD AFC model is one part of the UD HVDC models established based on the control system of Qinghai-Tibet interconneetion project. Case studies are conducted on the 2011 Qinghai-Tibet power network. The simulation results show correctness and necessity of the UD AFC model in improving the AC system frequency.
