摘要(Abstract)：

特高压交直流互联电网故障将给火力发电厂厂用电系统带来较大影响,根据厂用电系统一般带有电动机负荷的特性,基于PSD-BPA仿真平台,详细研究了电动机负荷的参数与建模方法,仿真分析了不同负荷模型下厂用电的电压特性。以兰溪发电厂厂用电系统为例,建立厂用电系统仿真模型,选取电网典型交直流故障,仿真分析不同运行方式及故障对厂用电电压的影响,为厂用电系统建模及仿真分析提供参考。
Faults in UHV AC/DC interconnected power grid have great impact on auxiliary power system for thermal power plants. According to the general characteristics of auxiliary power system with motor load, the parameters of the motor load and its modeling method are studied based on PSD-BPA, and voltage characteristic of auxiliary power with different types of load models is analyzed. This paper takes auxiliary power system of Lanxi Power Plant as an example to build a simulation model of auxiliary power system; it selects typical AC/DC faults in power grid to simulate and analyze the impact of various operation modes and faults on auxiliary voltage, providing reference to modeling and simulation analysis of auxiliary power system.
