基于控保协同策略的直流协调控制装置研制

Development of Direct Current Coordinated Control Device Based on Control and Protection Synergy Strategy

随着数据中心、电动汽车充电设施和分布式新能源等直流源荷的快速增加,传统配电网在接入、消纳等方面均存在明显的不足。利用电流差动、快速通信等方法进行故障识别与系统保护。以具体工程项目为基础,提出一套完整的控保协同策略,并以该策略为基础开发了一套协调控制装置。所提装置的应用可为直流配电网的稳定运行提供可靠保障。

With the rapid increase of direct current(DC)source loads such as data centers,electric vehicle charging facilities,and distributed new energy sources,the traditional distribution network has obvious deficiencies in terms of access and consumption.To this end,by use of current differential,fast communication and other methods,fault identification and system protection were implemented.Based on specific engineering projects,a complete set of control and protection coordination strategy was proposed,and a set of coordinated control devices was developed based on this strategy.The application of the proposed device can provide a reliable guarantee for the stable operation of the DC distribution network.
