新型失步继电器的微机实现

Noval Microprocessor-Based Implementation of a Out-of-Step Relay Scheme

暂态能量函数法已被广泛用来评价电力系统的暂态稳定性，但一般地仅是进行离线分析计算。Ｒｏｅｍｉｃｈ等提出了用能量函数法的新型失步继电器的方案，但尚未见到其用微机在线实现的研究。本文用微机实现了新型失步继电器．并在电力系统动模装置上进行了实验研究。通过实验，本文基本解决了工程应用中的一系列技术问题，并找出尚待解决的不足之处．为新型失步继电器的进一步改进完善准备了条件。

Transient energy faction methods have used for accessing the transient stability of electric power systems. The scheme of a out-of-step relay based on the methods has been implemented with a microprocessor in this peper. Power system model tests show that the new out-of-step relay has good performance.
