Power plant and substation electric quantity acquisition device-based testing system and method

Abstract

The invention discloses a power plant and substation electric quantity acquisition device-based testing system and method. The method includes the following steps that: step S10, whether a detection device and an acquisition device are in communication connection with each other is judged, if the detection device and the acquisition device are in communication connection with each other, step S20 is executed, otherwise, a test is terminated; step S20, whether the acquisition device completes the acquisition of the last electric energy meter is judged, if the acquisition device does not complete the acquisition of the last electric energy meter, step S30 is executed, if the acquisition device completes the acquisition of the last electric energy meter, the test is terminated; step S30, N electric energy meters are selected, an electric energy meter function testing instruction is transmitted to the acquisition device, and the acquisition device acquires and stores the function information of the N-th electric energy meter; step S40, the function information of the N-th electric energy meter is read; and step S50, the function information of the N-th electric energy meter which is stored by the acquisition device is read, and the function information of the N-th electric energy meter stored by the acquisition device is compared with the function information of the electric energy meter which is obtained in step S40, if the function information of the N-th electric energy meter stored by the acquisition device is consistent with the function information of the electric energy meter which is obtained in step S40, the electric energy meter processing function of the acquisition device is normal, and the method returns to step S20. With the power plant and substation electric quantity acquisition device-based testing system and method of the invention adopted, function testing and protocol testing of power plant and substation acquisition devices can be realized, so that the verification of the correctness of the functions, the accuracy of the acquired data, and the normality of the communication of equipment connected into the system can be facilitated.

Description

technical field [0001] The invention relates to the field of electric power metering, in particular to a test system and method based on electric power collectors of power plants and substations. Background technique [0002] With the development of the power company's business, the power company has continuously improved its management and technical level. As an important basis for supporting market decision-making, electric energy data has put forward higher requirements for the construction of electric energy metering systems, requiring richer data collection content. The data transmission efficiency and reliability are higher, and equipment from different manufacturers is required to have good interconnection and interoperability. The equipment connected to the newly built system should follow the unified technical specifications to ensure the uniformity of collection equipment functions and consistency of communication, which is convenient for future equipment selection....

AI Technical Summary

Problems solved by technology

[0005] 1. Each manufacturer is formulating its own communication protocol. The equipment and systems of different manufacturers cannot communicate with each other. Protocol conversion must be performed, which wastes a lot of manpower and material resources, and increases the number of failure points, causing system instability and increasing the difficulty of system operation and maintenance. ;

[0006] 2. In order to protect their own interests, some equipment manufacturers keep the protocol confidential, which brings many restrictions and unnecessary troubles to the expansion of the user system
