Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] The protection fixed value checking method of the present invention is to store the protection fixed value list of each protection equipment dispatched by dispatching in the database as the basis of fixed value checking through the new telemotor, and the new telemotor periodically calls the fixed value of each protection equipment. value information, and compare the call-up fixed value information with the fixed value information on the protection fixed value list stored in the database. Consistency check, accuracy check, selectivity check and sensitivity check are performed on the fixed value.

[0015] Such as figure 1 As shown, the database includes: A table, B table, C table and D table, A table is the latest protection setting list table, which is used to store the protection setting list issued by dispatching; B table is the historical protection...

Abstract

The invention relates to a protection constant value checking method used for a novel telecontrol machine. A protection constant value list, which is dispatched and issued, of each protection device is stored in a data base to be used as the basis of constant value check by the novel telecontrol machine; the constant value information of each protection device is summoned regularly by the novel telecontrol machine; the summoned constant value information is compared with the constant value information on the protection constant value list stored in the data base; if the constant value information changes, a warning signal of constant value information change is sent, the data base is updated, the consistency check, the accuracy check, the selectivity check and the sensitivity check are carried out on protection constant values. By using the method, the problems that the check of the current protection constant value checking method is not comprehensive, and the reliability is poor are solved.

Description

technical field [0001] The invention relates to a method for checking the protection fixed value of a new type remote machine. Background technique [0002] The relay protection setting value is closely related to the safe and stable operation of the system. In recent years, all kinds of relay protection setting calculation software have basically adopted the current mature methods and software technologies, providing a better solution for relay protection professionals. The calculation management platform improves the automation and management level of relay protection setting calculation work. However, in practical applications, there are still various defects, which cannot well meet the application requirements of relay protection. It is necessary to build a set of fully functional regional power grid relay protection setting value checking methods to guide the relay protection setting calculation and calculation. Check the fixed value to improve the accuracy and reliabi...
