调度自动化系统负荷切除和恢复功能的设计与实现

Design and Implementation of Load Shedding and Recovering Function in Dispatching Automation System

针对现有调度自动化系统没有提供专门的负荷切除和恢复工具的问题,综合考虑调度员所关心的与切负荷相关的因素,提出了基于调度自动化系统平台开发的调度负荷切除和恢复系统,介绍了设计思路和实现方案。系统提供了低频减载装置以及变压器绕组过载监视功能、负荷投切方案制定功能,以及手动和自动投切负荷功能,方便了调度系统投切负荷的操作。系统已在苏丹国家电力公司(NEC)投入运行,在菲律宾投入试运行。

In view of the situation that load shedding and recovering tools are not provided in current dispatching automation systems,a load shedding and recovering system is proposed based on the dispatching automation platform.By considering the factors related to the load shedding dispatchers concern,design and implementing schemes are presented.This system provides overload surveillance function of under frequency load shedding（UFLS） units and transformer windings,the plan making function of load shedding,and manual and automatic load shedding function,which provides dispatchers with great convenience in load shedding function of dispatching system.This system has been put into operation in National Electricity Corporation of Sudan and launched on a trial basis in the Philippines.
