摘要

当邻近电力系统发生故障时，采用多参数孤岛系统可以提高工业用户分布式发电电源供电的可靠性。本文概述了MIS应用可能存在的限制，这些限制与发电机组(GU)的有功功率控制和继电保护设置的特点有关。本文讨论了以频率和电压降为特征的电力系统运行模式的具体特征。事实证明，负荷参数对电力系统运行模式计算有重要影响，并决定了MIS算法和设置所定义的控制动作的可行性。对MIS的性能效率进行了详细的分析。

Features of implementing multi-parameter islanding protection in power districts with distributed generation units

Reliability of electric power supply of industrial consumers owning distributed generation sources (DG) can be improved by implementing multi-parameter islanding systems (MIS) in case of faults in the adjacent power system. The paper outlines possible limitations of MIS application, which are related to the features of active power control and relay protection settings of generation units (GU). The paper addresses specific features of power system operation modes characterized by frequency and voltage drops. It is proved that load parameters exert significant influence on power system operation mode calculation and determine the feasibility of control actions defined by MIS algorithms and settings. Detailed analysis of MIS performance efficiency is presented.
