摘要

随着新能源和高压直流输电等非同步电源的增多，电网同步惯量降低，进而带来电力系统频率特性的显著变化。同步调相机作为同步机具备惯性响应，可为系统提供短时频率支撑。文中首先介绍了同步调相机惯性响应原理及与同步发电机的相互作用。然后，以同步调相机的惯性响应应用为切入点，梳理了国外电网在改善电网惯性响应和频率特性方面所做的工作，包括电网同步惯性水平、提高同步惯量的措施、同步惯性对同步电网频率响应的影响等方面。最后，结合国外电网研究经验，分析了华东电网是否有必要应用同步调相机增强电力系统频率支撑，并提出了相关建议。

Abstract

With the increase of non-synchronous generators such as renewable energy and high voltage direct current transmission system

the inertia of power system has been reduced

which in turn leads significant changes to frequency characteristics of power system. Synchronous condensers as one type of synchronous machines has inertial responses

which provides short-time frequency support for the system. Firstly

the principle of inertial response of synchronous condensers and its interaction with synchronous generators are introduced. Secondly

taking the application of inertial response for synchronous condenser as entry point

the worldwide work on improving the inertial responses and frequency characteristics of power system is sorted out

including the synchronous inertia level of power system

the measurements to improve the synchronous inertia

the effect of synchronous inertia on frequency response in power system and so on. Finally

combined with the worldwide research experiences

the necessity for East China Power Grid to apply synchronous condensers to enhance the frequency support of power system is analyzed

and relevant suggestions are put forward.
