摘要
在用于检验继电保护的电力系统仿真中 ,仿真系统必须能够接收继电保护设备发出的各种跳闸与合闸命令 ,因此 ,除了对系统的正常并联运行进行仿真计算外 ,还需要仿真电力系统运行中的各种缺相状态。该文针对一个典型的单回路远距离输电系统 ,提出了相模域变换和多模块耦合算法模型 ,并对其各种缺相状态进行了仿真试验。试验结果表明 ,所提出的模型是正确的 ,能够满足实时仿真系统的要求。
In the power system simulation for relay testing, all sorts of signal from the switch will be sent and received. The normal operating states as well as the non-full-phase states of the power system should be simulated. Using a phase-modal similarity transformation and a multiple-module-coupled algorithm, this paper presents a simulation model of a typical single-circuit high-voltage long-distance power transmission system in its non-full-phase states. The simulation results on a PC show that the model of the system is correct and is able to meet the demand of the real-time simulation.
