摘要
详细介绍了单片机无功补偿控制器的硬件和软件设计。单片机的外围扩展采用ＳＰＩ接口芯片，简化了电路结构，可降低成本和提高可靠性。软件设计中详细讨论了ＣＴ极性的自动识别、功率因数测量方法以及简化编程的控制算法和抗干扰措施等问题。
The hardware and software design of reactive power compensation controller with micro- controller is introduced. With the serial interface ICs, it is possible to simplify circuit, reduce cost and get higher reliability. In software design, polarity identification of CT, Power factor measurement, control algorithm for simplifying program and anti - interrupt methods are discussed.
