配电自动化主站系统负荷转供协调控制方法研究

Research on Coordinated Control Method of Load Transfer for Distribution Automation Master Station System

目前配电站负荷转供控制目标单一,协调性较差,导致配电功率损耗较高。为解决该问题,提出新的配电自动化主站系统负荷转供控制方法,通过单边负荷转供控制、双边负荷转供控制和负荷-负荷转供控制3种方式增强负荷转供控制性,同时引入变压器、输电线控制配电自动化主站系统负荷,利用计算安全阈值、确定操作指数、获取安全系数实现配电自动化主站系统负荷转供控制。对比实验结果可知,所提配电自动化主站系统负荷转供控制方法功率损耗低于传统方法,说明负荷转供控制性较好,为相关领域研究提供理论基础。

At present,the load transfer control target of distribution station is single and the coordination is poor,which leads to high power distribution loss.To solve this problem,this paper puts forward a new distribution automation master station system load transfer for coordinated control method,through unilateral load transfer for coordination,bilateral load transfer for coordination and load and load transfer for coordination of three ways to enhance the load transfer for coordination,at the same time introducing control power distribution automation system is the main load of transformer,transmission line,calculating safety threshold,is used to determine the operation index,access to safe coefficient distribution automation master station system load transfer for coordinated control.Compared with the experimental results,the power loss of the proposed coordinated control method of load transfer and supply in the distribution automation master station system is lower than that of the traditional method,indicating that the coordinated control method of load transfer and supply is better,which provides a theoretical basis for relevant researches.
