摘要

由于现有电力系统仿真软件模型的局限性,在这种环境下只能模拟小范围内的频率波动。孤岛系统中相对较大的频率波动无法用它们来模拟。针对这一问题,研究了发电机组OPC控制逻辑,并对其进行了适当的简化。建立了用于孤岛运行分析的发电机组速度控制模型和保护模型。在PSASP7.0自定义环境中建立这些模型,并与该软件中的其他原始组件一起构成孤岛系统运行的控制仿真平台。以实际系统为例,对其运行状态进行了仿真分析,验证了所建仿真平台的合理性和实用性。

A Simulation Platform for Modeling Islanding Power Systems and its Application in Designing Stability Control Schemes
Because of the limitation of models in existing power system simulation softwares, only frequency fluctuations in a small range can be simulated in such environment. Relative bigger frequency fluctuations in islanding systems can not be simulated in them. To solve that problem, the OPC control logic of generating units was studied, and was simplified properly. The speed control model and protection model of generation units for islanding operation analysis were also developed in this paper. Furthermore, these models were set up in a user-defined environment of PSASP7.0 together, with other original components in the software, comprised a control simulation platform for islanding system operation. Its operational status was simulated and analyzed in a real system as an example, which proved that the reasonableness and practicality of the established simulation platform.
