Method and system for impact analysis of power communication relay protection business

Abstract

The invention relates to a method for impact analysis of a power communication relay protection business. The method comprises the following steps: (1) collecting communication network alarm information in a real-time manner and carrying out normalization processing; (2) matching the alarm and a transmission channel loading the relay protection business; (3) carrying out correlation analysis on the alarm of a relay protection channel; (4) searching whether the transmission channel loading the relay protection business has a main transmission channel; (5) analyzing a spare transmission channel according to steps which are the same as the steps of the main transmission channel; and (6) analyzing impact on the transmission channel according to the alarms on the main transmission channel and the spare transmission channel of the relay protection business. The invention further discloses a system for impact analysis of the power communication relay protection business. According to the method for impact analysis of the power communication relay protection business disclosed by the invention, special requirements of the relay protection business are considered, the impact on the business is subdivided, the impact degree of a fault on the relay protection business can be analyzed, and accuracy of an analysis result is improved.

Description

technical field [0001] The present invention relates to a method and system for business impact analysis, and more specifically relates to a method for analyzing power communication relay protection business impact and its system. Background technique [0002] Traditional power communication operation and maintenance management mainly focuses on real-time monitoring and fault handling of the communication network from the equipment level and network level, so as to ensure the normal operation of power grid communication services. With the acceleration of the smart grid construction of the State Grid Corporation of China, higher requirements are put forward for the operation and maintenance management of electric power communication. The operation and maintenance of the communication network needs to be upgraded from the traditional equipment-oriented and network-oriented Rise to active operation and maintenance. Therefore, it is of great significance to research and apply t...

Problems solved by technology

However, in electric power communication, the definition of service level agreement has not yet been carried out, especially for different businesses, which makes the traditional business impact analysis method not fully suitable for power communication relay protection business impact analysis. , there are mainly the following problems:

[0004] (1) The established service resource model does not consider the special requirements of relay protection services, such as delay, transmission bandwidth, transmission system, active and standby routes, etc.;

[0005] (2) Although the analysis of the root cause of the network event is carried out, which reduces the amount of analysis and calculation, it does not subdivide whether the event has an impact on the business, and the analysis of the root cause is not based on the specific resource object of the transmission channel
