基于站域保护的简易母线研究

Study on Substation-area Protection Based Simple Bus Protection

根据变电站低压母线保护需要,利用基于全站数据信息的站域保护,实现简易母线保护功能。通过现有低压母线保护实施的难点分析,结合智能化变电站技术应用,设计站域保护简易母线实施方案,给出原理及动作过程分析。该实施方案在新一代智能变电站中得到实际应用,验证了可靠性及技术优势。

According to the demand of low voltage busbar protection in substation, the function of the simple bus protection is realized by using the substation-area protection based on the information of the station. Through the analysis of the difficulties of the existing low voltage busbar protection, with the application of the smart substation technology, the design of the simple bus implementation scheme, the principle and the action process analysis are given. The implementation scheme has been applied in the new generation of smart substation, which proves the reliability and technical superiority.
