摘要
采用3/2接线的变电站系统有着自己特殊的电网结构和保护配置方式,但目前电网故障诊断优化模型在具有应用普遍性的同时,并没有很好的考虑这种特殊的接线方式,也就不能充分满足3/2接线系统对故障诊断的要求。优化诊断模型是通过目标函数来体现和实现的,基于此,通过对现有模型的深入研究,将3/2接线系统的接线方式及其保护配置方式反映到目标函数中,从而使改进后的目标函数能够满足和适用其对故障诊断的需求。最后,通过一个典型的仿真算例证明了此模型的合理性和正确性。
Some substations using 3/2 connection mode is provided with special net sturctures and configurable modes of protective relay, but actual optimization model for faulty diagnosis bears universality of application simultaneously, does not calculate well the special connection mode, therefore, the foregone model has been incapable of satisfaction for 3/2 connection mode system. Optimization model is incarnated and actualized by objective function, based on the research for existing model, special connection fashions and configurable modes of protective relay for 3/2 connection mode system are embodied through objective function, consequently, the function ameliorated is capable of satisfaction and application for faulty diagnosis of 500 kV electric network. Eventually, the reasonability and validity of model are testified through a typical stimulant example.
