Design And Implementation Of Intelligent Remote Communication System For Power Substation

In recent years, with our country economy development, and reconstruction of urban and rural power grid construction in full swing, large substation construction and expansion, bringing with very tight supply personnel, unmanned substation to highlight the growing importance of, not only 110 k V, 35 k V low-voltage substations required to achieve unattended, requires more than 220 k V EHV substation and also gradually develop unmanned Management, This requires remote communication devices need to have more features, more performance and more stable operation.Based on the collection and access to relevant literature, in Linux, Apache, Mysql, Php high reliable and stable third-party software, based on the real-time database server through the self, the station, the development of remote communication module, a friendly man-machine interface design completion of intelligent features such as remote communication system, specifically designed and implemented as follows:1) Design of real-time database SERVER, internal communication protocol, to create the IPC CLIENT and IPC SERVER interaction processes, through the IPC CLIENT to the external interface module provides services, such as communication processing module, and will obtain the acquisition data classification, caching, dump, distribution processing, such as real-time database data synchronization via the IPC SERVER, complete the on-site internal data sharing and real-time data communication;2) Based substation communication protocol and device-based remote communication protocol developed master the appropriate protocol module, sharing function interface in TCP, UDP, serial port interface and real-time database wrapper function on the completion of the reading and other basic requirements of the Statute of communication, real-time database data on remote communication support and scheduling data delivery;3) According remote communication requirements, design and interactive interface, introduced by the device template file, perform device configuration, channel configuration, protocol configuration, remote communication configuration, configuration, user profiles and other functional configuration; secondly through the pages of the protection device operations and real-time monitoring; finally through the pages of various types of protective event history log, generated during the operation of the system for maintenance, to provide users with comprehensive services;Main focus for the design of real-time database server to achieve IPC CLIENT-side communication processing module and remote communication protocol developed master, participate in the development of human-computer interface design and configuration of some of the data distribution process.
