6 kV配电系统继电保护综合分析与整定方法的选择

摘要

To solve the existing problems in the design and layout of power supply sys-tem of the old enterprise, improvement revamping was made to the relay protection in the 6 kV power supply system. Setting values were selected based on the actual conditions of the power grid to reduce economic loss caused by false protection action and improve reliability of enterprise power supply.%针对老企业供电系统设计布局存在问题，做好6 kV供电系统继电保护改进工作，综合电网本身情况选择定值整定方法，以减少保护误动作造成的经济损失，提高企业供电的可靠性。
