丰白系统微机稳定控制装置的研究

The Study of Microprocessor-Based Stability and Control Device Applied in Fengbai System

介绍一种新型的就地判别式稳定控制装置。它引入装置安装处的母线电压和各线路电流，由电压和电流来判断故障情况，并根据不同故障对系统稳定的的影响，按定值执行切机。本文主要介绍装置的硬件构成和软件功能。目前，该装置已应用到东北丰白系统的东丰、梅河、哈达湾和丰满水电厂。

A new type of microprocessor-based device based on-the-spot is introduced.The device deals with the voltage of busbar and the current of transmission lines which are connected to the device.The device detects type of fault by means of the voltage and current and trips generators according to the settings.The hardware and software of the device are mainiy described.Today,the device is applied in Dongfeng substation,Meihe substation,Hadawan substation and Fengman hydropower plant of Fengbai power system.
