东莞电网自动电压控制的实现与运行

摘要

Taking Dongguan power grid for example, this paper introduced the necessity to construct an automatic voltage control (AVC) system and expounded the implement method, control strategy and safety precautions of AVC. After the closed loop was put into operation, the voltage eligibility rate was improved and the power grid loss was reduced, which verifies the effectiveness of AVC function, to make the reactive voltage management of power grid realize safe, stable, high-quality and economic operation.%以东莞电网为例，介绍了建设自动电压控制（AVC）系统的必要性，并阐述了AVC系统实现的方法、控制策略及安全保障措施。经闭环投运，提高了电压合格率，降低了网损，验证了AVC功能的有效性，使电网无功电压管理真正实现了安全、稳定、优质、经济运行。
