分布式VQC的实现方式与应用

The Implementation Mode and Application of Distributed VQC

在枣庄地区电网电压无功综合控制技术方案中,根据现场实际运行情况,变电站电压无功综合自动控制(VQC)采用了以下几种实现方式:自带I\O(系统的VQC、利用自动化系统后台监控系统的VQC实现方式、自动化系统网络VQC以及半独立的VQC实现方式。对各种方式进行了仔细分析和研究,提出了一种新的实现方式。经过山东枣庄电网的试运行表明,效果良好。

In the program of Zaozhuang power grid voltage reactive power control technology. According to the actual operation of the scene VQC using the following methods to achieve： the independent VQC with their own I/O system, the half- independent VQC. According to the operational situation in substations, the modes of VQC are compared and analyzed. The advantages, drawbacks and the main technical problems are pointed out. On this base, a new reformative mode VQC is presented. After the trial operation for power grid in Shandong Zaozhuang shows that the result is good.
