The application philosophy, limitations, and testing methods for the automatic voltage control (AVC) system of the power grid are described in this guide. The testing for reactive power control based AVC systems in the power grid is applied.

This guide describes the application philosophy, limitations, and test methods for the automatic voltage control (AVC) system of the regional power grid. This guide applies to the testing of the AVC systems in regional power grids.

The purpose of this guide is to describe the methods of testing the functions and technical performance of regional AVC systems, with a view to finding the potential defects of AVC systems and improving the operational performance of AVC systems.
