摘要
微机保护装置已在生产实际中得到了广泛的应用。作者描述了将PLC 引入保护中且与微机结合实现保护装置的原理、方法。其中心在于用PLC 以实现保护装置的逻辑控制,而以单片微机作为测量、分析、计算的基础。作者也描述了它们之间的接口及紧急情况处理等。通过试验研究,所设计的装置符合继电保护的要求。
The protective device realined by microprocessor has been found wide application in practice this paper described prinliples and ways in which PLC is used for protection The core of this paper is a logical controller realined by PLC,and microprocessor is used as the basis for testing,analyzing and calculation and also states the interface ways between PLC & microprocessor and urgent case processing is also discussed Having been run on simulated experiments for many times,the device is fit for the prescript of relay and should be apply it practice in future
