This design is mainly for the 10 kv substation relay protection design, reliable relay protection system is an integral part of the substation safe operation and stable power supply, mainly used in a system of monitoring, measurement and protection. By all sorts of power relay protection system and non-electricity protection equipment to cooperate with each other. Through the provision of original design data of the detailed way of setting calculation to determine the protection, type, and relay protection setting value of instruments, and select the ppropriate relay can make the substation fault in the state of relay protection system is reliable, fast and selective removal of fault component or a fault signals, so as to protect equip...
