Calculation method of automatic adjustment and coordination based on cobase system

Abstract

The invention discloses an automatic setting coordination calculation method based on a cobase system. The method mainly includes two steps of rule definition and setting coordination calculation, wherein the rule definition respectively includes three parts of basic information definition, coordination rule description and coordination algorithm description, the three parts are required to be pre-defined before the starting of the setting coordination calculation, after the starting of the setting coordination calculation, the rule definition is automatically called according to information of observation points, and relevant information of the observation points are generated according to the rule definition. According to the automatic setting coordination calculation method based on the cobase system, an integrated platform is used as a source of initial data, and rules are simply configured to drive a relay protection setting calculation system, so that individualized requirements of power grids of different areas are well met, simultaneously, work efficiencies can be improved, setting time is shortened, and safe running of the power grids is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an automatic setting coordination calculation method based on a coBase system. Background technique [0002] Relay protection setting calculation is a very complicated and error-prone work. Relay protection setting calculation work often starts with parameter collection and input, through the main process of coordination calculation and device setting calculation, and finally enters a process including review, release, receipt At the same time, various protection devices for power grid relay protection are an important part of the power system, and they play a role in ensuring the safe operation of the power system. As an important part of the relay protection system, the relay protection setting calculation is used. The function of the device is to quickly and correctly judge when the power system fails or is in an abnormal operating state, so that the protection device ...

Problems solved by technology

[0003] The traditional setting calculation relies on manual experience setting mode, which results in long calculation period, high labor intensity, low work efficiency, and is not conducive to the requirements of power grid protection sensitivity, quick disconnection, selectivity and reliability; with the economic development With the development of the power grid, the scale of the power grid is becoming more and more complex, and the operation of the ring network is becoming more and more common, which brings great challenges to the setting calculation work. At the same time, the setting rules of the power grid in various regions need to be adjusted accordingly with the development of the power grid. Software, the value of the setting rules is realized through programming technology, and the change of the rules needs to be realized through modification

[0004] The existing setting calculation system does not significantly display the difference in the setting value in the graph, nor does it display the setting value of different nature with different identifiers, so it is not conducive to the safe operation of the power grid
