摘要
模糊控制技术不需要建立精确的数学模型,分析解决多变量非线性系统具有明显的优点。为实现以官地水电站1、2号机组作为电源端点控制月城地区潮流的目标,因系统存在多变量、非线性和难建模等特点,本文提出了将模糊控制技术与常规PID控制的相结合,设计并实践了一种对电网潮流控制简单有效的控制方案。实际运行结果表明,通过模糊控制与常规PID的结合,能有效的控制电网潮流变化在设定范围,具有重要的工程意义。
To establish a precise mathematical model is needless , fuzzy control technique has obvious advantages to solve the multi-- variable nonlinear system. In order to realize that 1, 2 hydroelectric generator of Guandi Hydropower station as a power source endpoint to control power flow of Yuehen area, due to the existence of multiple variable, nonlinear and hard to model characteristics, this paper presents a simple and effective control scheme with the fuzzy control technology and the conventional PID control combination to design and practise a kind of power flow control. Practical operation results show that, the system with adaptive performance, can adjust when encounter interference, is not only simple and practical, but small overshoot, effective.
