地区电网AVC系统设计与实现

Design and realization of AVC system about area power system

电压和电网损耗是电力系统重要的指标。提高电压合格率和降低电网损耗是电网企业一项非常重要的工作。目前在地区电网中已广泛使用的无功补偿和调压手段是变电站无功电压控制装置VQC,但是VQC存在着不能有效处理全网范围内的无功优化问题和维护工作量大等诸多不足。AVC是地区电网无功调度发展的最高阶段。介绍了地区电网AVC系统的总体设计方案、控制模式、控制策略等,并针对当前无功电压控制的现状,提出了具体解决方案。

The voltage and the electrical network loss are important target of the electrical power system. Improving the voltage qualified and reducing the electrical network loss are an important work of the grid enterprise. In the current, the means of reactive power compensation and voltage regulation is VQC, which has been widely used in regional power grid. But there are many inadequacies with VQC, which cannot effectively process Reactive Power Optimization in the entire net scope. And the maintenance of VQC is difficult. AVC is the highest stage of the regional power grid reactive scheduling. This article introduces the area power system AVC system, including system design plan, the control pattern, the control strategy and so on, proposes a concrete solution.
