The invention provides an electric energy quality management system multi-machine main / standby realization method, which comprises the following steps that S1, creating a main control module process operates, a server heartbeat message timing service and a server information monitoring timing service synchronously, wherein the server information monitoring timing period is greater than or equal totwo server heartbeat timing periods; S2, creating a synchronizer thread; synchronous communication of the communication message among multiple machines is realized through the synchronizer; S3, registering a multicast service; s4, initializing a local server information pool data structure; and after obtaining the heartbeat message of the server, updating the content in the corresponding server record in the message data. In the embodiment of the invention, aiming at the problems easily occurring in the application field of the power quality management system, the mode is adopted, so that theredundancy of the power quality management system is enhanced, the robustness of the system is improved, and an expected effect is achieved in the deployed field.
Description
Technical field [0001] The invention belongs to the field of multi-machine main and standby power quality management systems, and in particular relates to a method for realizing multi-machine main and standby power quality management systems. Background technique [0002] The power quality management system mainly includes a collection module, a calculation and analysis module, a storage module and a display module. Each module completes the follow-up work of the previous module in turn. Each module complements each other to realize the power quality management system function. When a problem occurs in any link in any module, the subsequent modules in the power quality management system will not work normally, which will affect the normal use of the power quality management system. The application field of power quality management system has become more and more extensive, and has gradually attracted attention and attention. The stability of the power quality management system i...
