Research And Application Of Relay Protection And Fault Information System

In the large-scale power system failure,dealing with power grid accident and recovery system depends largely on the speed of the grid to determine the operation and analysis of information.Therefore,how to get the real-time information of fault quickly,analyze the fault accurately,recover the system quickly and effectively,improve the stability of power system and ensure the continuous and reliable power supply become the problem of relay protection.Yulin Power Supply Bureau in conjunction with Yulin power grid relay protection status quo established a relay protection and fault information system,making the power grid in the event of failure in time to effectively grasp the fault information on the power grid to effectively determine the accident,handling and rapid system restore.In 2011,in order to improve the informatization and intelligence level of Yulin power grid dispatching and realize the effective monitoring and relay protection action analysis and processing of substation relay protection equipment,Yulin Power Supply Bureau in-depth analysis of the overall structure of Yulin power grid,Sets for relay protection and fault information system of Yulin power grid.Based on the actual situation of relay protection in Yulin power grid,the status quo and background of relay protection and fault information system in China are briefly introduced.The general design of relay protection and fault information system is put forward according to the general structure of Yulin power grid.Based on the proposed framework of the relay protection and fault information system design,and through the 103 communication protocol Yulin power grid fault data transmission standardization,combined with 103 power system communication protocol in the actual project problems encountered in the corresponding solution Program.Finally,relay protection and fault information system in Yulin grid elaborate practical application,analyze their strengths and weaknesses,put forward the corresponding solutions,and to improve future protection and fault information system makes a further overview.
