电力系统继电保护不稳定的原因分析及解决措施

Analysis of the Causes of Unstable Relay Protection in Power System and Solutions

随着社会经济及科学技术的日益发展,人类的生活水平有了极大的提高,对电力资源的需求也在不断增多。为了迎合目前人类对电能的需求,日益拓展了电力系统规模,如此就促使电网的结构逐渐复杂。继电保护属于电网中十分关键的部分,一旦其产生不稳定情况,必定会给电网总体安全运行造成不良影响。基于此,文章对电网中继电维护不稳定出现的原因进行了详细研究,并提出了有效的处理措施,以期能为相关人员处理几点不稳定情况,为其安全运行带来一定的帮助。

With the continuous development of social economy and science and technology, the living standard of mankind has been greatly improved, and the demand for power resources has also been on the rise. In order to meet the current human demand for electrical energy, expanding the scale of the power system, so that the structure of the grid gradually complicated. Relay protection is a very important part of the power grid, once instability occurs, it will certainly have an adverse effect on the overall safe operation of the power grid. Based on this, the article makes a detailed study on the causes of unstable instability in the maintenance of power network, and puts forward effective measures to deal with some unstable situations so as to bring some help for its safe operation.
