| Abstract: | The principle, characteristics and algorithms of microprocessor based fault disconnection device are introduced in detail. The device adopts 80C196 microprocessor as the CPU of relay; the frequency measurement unit employs hardware to measure frequency, the measurement precision is higher; the under frequency disconnection unit has perfect, reliable blocking measure to prevent mal operation; the under voltage disconnect unit has reliable criteria to detect three phase voltage failure. The device has been verified through different dynamic model tests and put into site operation. |
