Intelligent algorithms library model aiming at relay protection device

Abstract

The invention discloses an intelligent algorithms library model aiming at relay protection devices, which comprises an algorithms library, an algorithm adapter and an algorithm resolver. Firstly, a serialization result of a control unit is used as an input value of the algorithm adapter, a corresponding algorithm formula is extracted from the algorithms library and then fed back to the algorithm resolver by the algorithm adapter, iterative calculation analysis is performed by the algorithm resolver, and a calculation result of the algorithm resolver is fed back to the algorithm adapter and then processed to be output by the algorithm adapter. After the intelligent algorithms library model aiming at the relay protection devices is used for a power system, the adaptive range of state evaluation and warning detection of the protection devices is enhanced, and state overhaul evaluation of all of the protection devices, which are performed once every weeks or months, are improved to be a mode that on-line state evaluation and warning detection are performed in real time. Additionally, overhaul decision algorithm analysis of the algorithms library model is utilized to provide a reasonable and feasible overhaul recommendation for operation management personnel, the workload of the personnel is greatly reduced, and the work efficiency is increased.

[0002] With the development of the scale of the power grid, the number of equipment continues to increase, and the technical level and reliability are rapidly improved. The traditional equipment regular maintenance mode has been difficult to adapt to the new management requirements.

At present, the condition-based maintenance evaluation of domestic relay protection devices can only be carried out regularly, and can only be modeled for fixed condition-based maintenance guidelines, and the evaluation algorithm cannot be flexibly configured and meet the requirements of complex calculation formulas

There is a lack of general algorithm formulas, and it is not possible to flexibly configure algorithms for different types and models of protection devices

The algorithm only depends on the evaluation guidelines, and equipment suppliers cannot participate in the design of the algorithm
