Abstract

The invention provides an inspection method of a 104 protocol channel of a 500 kV substation centralized monitoring system. The inspection method is characterized by comprising the following steps of step 1, establishing a dynamic network model between a scheduling real-time data network and a substation which are accessed into a centralized control center and step 2, achieving the automatic inspection function on a 104 protocol network of the substation centralized monitoring system by two methods of regular inspection and fault automatic excitation inspection. According to the inspection method of the 104 protocol channel of the 500 kV substation centralized monitoring system, the problem of the communication failure between a plurality of substation 104 protocol channels and the centralized control center is caused due to the fact that the fault is easy to produce in the past is solved, the inspection method is established in the centralized monitoring system and used for effectively analyzing the communication state of the 104 protocol network, and the problem link is effectively found when the communication fault of one substation and the centralized monitoring system is produced.

Description

Technical field [0001] The present invention involves a compassion for the 104 -conservation system of the centralized monitoring system of a 00KV substation. Background technique [0002] The centralized monitoring system of 500KV substation has been connected to 23 500KV substation. The IEC60870-5-104 Period Channel is based on the combination of application layer and TCP / IP transmission function.The main duty channel of the monitoring system.The 104 Standard Channel runs the data network in real time in the power system. The main network is generally a ring topology structure, consisting of a large number of routers, switches and other network devices.Any network device failure may cause a network control center and the 104 channel communication failure of the integrated control center, and some intermediate hub nodes faults will cause multiple substation 104 channels and the communication center communication center.At this stage, an effective means of establishing an effecti...
