摘要
从中小型变电站的数学模型入手,通过数学模型地推导,指出单一的PLC控制在无人变电站控制决策中无法高速处理数据的局限,由此提出以DSP+PLC主从式结构实现无人变电站的电压和无功模糊智能自动控制策略。具体介绍了采用DSP为计算核心完成基于模糊边界的电压无功九域图控制策略判断,由PLC完成具体电气控制操作的实施方案。
According to the mathematical model of transformer substation, this article points out the shortcoming of the automatic control system based only on PLC, and presents an improved system based on DSP+PLC, which adopts fixed voltage and fuzzy reactive power borders. This article introduces in detail how to choose the fuzzy automatic control algorithms based on the reactive power/voltage comprehensive control theory, and at last, the load tap changers controlled by the PLC.
