Problems solved by technology

[0004] The current effect of multi-source data identification based on other system information is not satisfactory. The main reason is that the cost of interconnection between the Guxin system and other systems is too high. The problem is that because the SCADA system model is updated quickly, the models on both sides often do not match, which affects the actual effect. At the same time, the system interconnection will also have a greater impact on the stability of other systems. Finally, this method will also improve the user's economy. Therefore, under the theory of multi-source data interconnected with other systems, in fact, the maintenance data of the guarantee system cannot be effectively eliminated, and the practicability of the guarantee system cannot be essentially improved

Embodiment Construction

[0025] like figure 1 As shown, it is a schematic flow chart of a preferred embodiment of the method for identifying maintenance data of relay protection devices according to the present invention, which includes the following steps:

[0026] S11. Obtain the protection event sent by the guarantee system, and when the protection event is a protection exit event, judge the protection exit event received within a preset time;

[0027] S12. When the protection exit event is greater than the preset number, if the current protection setting value is the preset protection reset value, then compare the current protection setting value with the protection setting value of the last inspection, if inconsistent , then set the current protection setting as the preset first protection setting;

[0028] S13. If the current soft platen value is the preset soft platen reset value, compare the current soft platen reset value with the soft platen value of the previous inspection, if they are inc...

Abstract

The invention provides a method and a system for identifying overhaul data of a relay protection device. The method comprises the steps of acquiring a protection event sent by an information protection system; if the protection event is an exit protection event, determining the exit protection event received within a preset time; if the quantity of the exit protection events exceeds the preset quantity, and the current fixed protection value is the preset protection resetting value, comparing the current fixed protection value with the fixed protection value obtained by previous polling; if the current fixed protection value is not the protection resetting value, setting the current fixed protection value as the preset first fixed protection value; determining the soft strap value, three-phase voltage value and protection version number by the same way; adding the obtained total action times, interrupting connection times, action time and overhaul times of the protection device to obtain the adding result; if the adding result is within the preset first range, determining that the protection event is overhaul data; if the adding result is within the preset second range, determining that the protection event is the action data. With the adoption of the method and the system, the information protection overhaul data can be effectively identified by analyzing the protection device body information.

Description

technical field [0001] The invention relates to the technical field of electric power system relay protection, in particular to a method for identifying maintenance data of a relay protection device and a system for identifying maintenance data of a relay protection device. Background technique [0002] At present, the relay protection information system has been built in a large area across the country, but the practical effect of the system is restricted by many factors, and there is still a certain distance from the user's expectations. One of the most important factors restricting the practical application is The system receives a large amount of maintenance data of relay protection devices, which overwhelms important protection normal action information. Therefore, in order to improve the practical level of the system, identification and elimination of maintenance data has become an important research direction. [0003] At present, the identification of maintenance da...
