Abstract


Substation Monitoring and Control System’s main feature is that all intelligent substation electrical equipment monitoring and control. It smart for electrical equipment in substation telecontrol and telemetry and remote functions. Ensuring the substation work in the normal operation and maintenance later, as well as industrial enterprises in the production of the normal operation of electrical equipment. Based on this point, I chose the substation monitoring and control system of electronic communication as my Master of Engineering thesis topicIn this paper, on the industrial enterprises in substation monitoring system composition, content, functions and features have been studied, according to the functions of monitoring and control system to points can be divided into centralized monitoring and control system and the hierarchical and distributed monitoring and control system. Centralized monitoring and control system is suitable for small and low-voltage substation automation systems. If there is high-voltage electrical equipments in the substation the automation systems are stratified Distributed Control System.In this paper, the studying electrical monitoring and control system are from a foreign chemical enterprises. The project has two substations, in order to achieve the telemetry and remote monitoring system of functional components layer distributed architecture design. To address the district substation devices in situ monitoring devices at the establishment of a plant substation PLC monitoring sub-stations, to resolve the monitoring system job MODBUS protocol and inverter job PROFIBUS-DP protocol compatibility problem and on-site surveillance of low-voltage electrical equipment and variable frequency motor self-starting functions.In order to complete the monitoring system and instrumentation interlock system, the communications monitoring system at the management of the addition of a communications manager. The completion of the monitoring system data communication signal transmission chain again Instrument to Instrument DCS.To resolve all questions of communication, application of suitable monitoring system software, the completion of the project all the intelligent electrical equipment remote control and telemetry functions. Solved with a monitoring and control system to complete both the monitoring system and instrumentation interlocking system.
