摘要 摘 要 I I 摘 要 电压是电能质量的重要指标，电压质量对电力系统的安全与经济运行，对 保证用户安全生产和产品质量以及电器设备的安全与寿命有重要的影响。电力 系统的无功补偿与无功平衡是保证电压质量的基本条件，有效地控制和合理的 无功补 偿， 不仅 能保证 电压 质量 ，而 且提高 了电 力系 统运行 的稳 定性 和安 全 性，降低电能损耗，充分发挥电能经济效益。邢台电网具备实现 AVC 自动电压 控制的技术条件和运行管理模式，迫切需要实现无功和电压的自动优化控制， 对邢台电网安全、稳定、经济运行具有重要意义 首先，本文系统阐述了邢台电网 AVC 系统的模式构成，邢台电网 AVC 实 现是基于电力系统调度 O PEN3000 一体化设计，自动实现运行指标控制和目标 数据的统计。其次，深入研究了邢台电网 AVC 的系统构成及控制策略，它是基 于动态分区的分级控制策略的无功电压自动控制。同时，详细阐述了动态分区 分级控制模式的原理。最后，总结分析了邢台电网自动电压 控制(AVC)系统的 建设情况和运行效果，介绍了邢台电网 AVC 系统实施过程，并以邢台电网三座 110kV 变电站闭环运行数据为例，对 AVC 系统控制策略应用问题进行分析总 结，提出后续改进计划。 关键词：邢台电网；自动电压控制；无功控制；控制策略 Ab Abstract II II Abstract Voltage is an important index of power qualit y, voltage quality of power system security and economic operation, to ensure user safety in production and product quality as well as the electrical equipment safety and life has an important influence. Power system reactive power compensation and reactive power balance is the basic condit ion to ensure the quality of voltage, effectively control and reasonable reactive power compensation, not only can ensure the quality of voltage, and improve the stability and safety of the power system operation, reduce the loss of electrical power, give full play to the economic benefits of electric power. Xingtai power grid AVC automatic voltage control of technical condit ions and the operation management pattern, an urgent need to achieve automatic optimization of reactive power and voltage control, of Xingtai power grid security, stability, economic operation has important significance First, this paper expounds the mode of Xingtai power grid AVC system composition, Xingtai power grid AVC implementation is based on the power system dispatching OPEN3000 integration design, automatic operation control and target data statistics. Second, further study of the Xingtai power grid AVC system structure and control strategy, it is a hierarchical control strategy based on dynamic partitioning of reactive voltage automatic control.
