自动电压控制在城市电网中的应用

Application of automatic voltage control in urban power grid

随着电网规模的不断扩大,对于电网电压控制的要求也越来越高。在传统的建立在变电站中心基础上的控制手段也必须进行升级,建立自动化电压控制系统对于优化协调无功功率和稳定地区电网电压有着重要意义。本文通过分析自动电压控制的发展和存在的问题,以及城市电网中电能质量的一些不足,研究了自动电压控制系统的发展趋势和方向,并且最终得出了一些结论,力图为自动电压控制系统在城市电网中的应用提供一些参考。

With the continuous expansion of the scale of the power grid,the requirement for the power grid voltage control is also growing higher and higher.The traditional control method based on the substation center must be upgraded,and the establishment of the automatic voltage control system is of great significance to the optimization of the reactive power and the stability of the regional power grid voltage.In this paper,by the analysis of the development and the existing problems of automatic voltage control,I summarize the problems in city grid power quality and the development trend and direction of automatic voltage control system,and finally some conclusions are drawn,trying to serving as a reference to the development in the automatic voltage control system used in urban power grid.
