电站测试用负载阵自动控制系统设计

Design of Load Array Automaticcontrol System for Power Plant Testing

针对目前电站电气性能测试对测试用负载的控制需求,以可编程控制器(PLC)为核心开发设计了一套电站测试用负载阵自动控制系统,主要内容包括大功率可调负载阵设计,上位机软件设计,PLC的控制过程与软件设计等,该自动控制系统改变了过去负载调节自动化程度低,适应性差的缺点,为电站电气性能自动测试的实现提供了技术保障。

Aiming to demands of testing load controlling for power plant electrical quality, this paper designs a set of testing load automatic control system with the core of PLC. It mainly introduces design of high power and adjustable load array, design of computer platform software, control process and software development of PLC. And this automatic control system changes the past shortage of low level of load automatic adjustment and weak accommodation; therefore it provides the technical guarantee to realize the automatic testing of power plant electrical quality.
