[Abstract]:Fault information processing system is a data platform for remote management of power network automation. It can upload and collect data of power grid operation in substation in real time, analyze the cause of failure and deal with fault events for dispatching staff. Evaluation of relay protection equipment to provide strong support, at the same time greatly improve the degree of automation of power grid management, can quickly deal with failures, stability of power grid operation. This system is based on the IEC61850 standard specification, in-depth study of the background, composition, structure and modeling ideas of the IEC61850 standard. The modeling method of intelligent device object in IEC61850 standard is described in detail, and an example is given to illustrate the characteristics of large amount of data and high real-time requirement of fault information processing system. This system introduces the method of combining real-time database with traditional database, which makes the data collection of substation relay protection equipment stable, safe and fast to the master station dispatching staff. Communication service is a bridge between the system and the substation. The communication mechanism of the main station is explained in detail in this paper, and the UDP communication mode is introduced. And the encapsulation of the message structure is explained in detail. The fault recorder data of real-time monitoring relay protection equipment in substation is regarded as the important basis of fault diagnosis by analyzing the fault recording file. In this paper, a fault judgment method based on the change of sudden current is proposed, and the corresponding formulas and algorithms are given, which can be used to judge the types of faults. The fault information processing system makes full use of computer technology to calculate fault distance synthetically from single terminal and double terminal location, which greatly improves the time limit of power network fault processing. The reliability of fault judgment is improved, and the data processing ability of dispatching center is increased.
