Design of Operating Fault Diagnosis System of High Voltage Power Grid Based on GOOSE Communication Technology
Generic object oriented substation event(GOOSE)communication technology is a real-time automatic communication protocol based on Ethernet,which is widely used in the field of power system protection and control.It can provide fast and reliable data exchange,especially suitable for fault diagnosis of high voltage power grid.As the main mode of power transmission,the stability of high voltage power grid is very important for the safe operation of the whole power system.Power grid faults,including short circuit and equipment faults,not only affect the reliability of power supply,but also may cause a larger power supply interruption.Therefore,developing an efficient fault diagnosis system is of great significance for finding and handling potential faults in advance.The fault diagnosis system of high-voltage power grid operation based on GOOSE communication technology realizes rapid and accurate fault diagnosis of high-voltage power grid through three steps:automatic fault detection,real-time data processing and fault diagnosis and evaluation,and the effectiveness and practicability of the system are verified by application tests.
