Design Of Hydropower Station Monitoring System Based On ECS

Hydropower station monitoring system is to ensure safe, stable and reliable operation of the core part, holds an important place in the construction of hydropower station, this system also can reflect the national most automation technology development level. Now research based on ECS(distributed electrical control system) of hydropower station monitoring system, achieve the requirement of advanced technology, safe and reliable control, take advantage of ECS powerful structure configuration, control system together with peripheral superior monitoring function.This paper according to the requirements of the hydropower station monitoring system design and the principle of the control system is divided into power plant control level and field control level, based on the structure of dual redundant Ethernet network. Was proposed based on hydropower station monitoring system design scheme of ECS, under a machine with a central zhejiang ECS- 700 system implementation in situ control unit and PC based on VisualField monitoring software, and the system structure configuration design. According to the control unit to realize the function of the unit in situ and role, and the structure of the electrical control system is given, the control unit of the design content mainly includes: determine the signal measuring point of the unit, the hardware selection and software in the configuration, the final communication to carry on the design of the control unit.According to the design specification, hydropower station computer monitoring was carried out on the PC monitoring system design, mainly includes: engineers permissions Settings; Alarm, report to the design of system; The design of the implementation of the monitoring configuration screen, real-time monitoring. Generating set monitor screen realize the dynamic display of the parameters, key operation guide implementation unit, reduce the failure rate; Design of monitoring friendly interface, simple image level, convenient operation and maintenance, can avoid the wrong operation.Finally, to debug the designed control system, for the field control unit designed software and hardware testing, mainly includes: the channel debug, functionality, and debugging, monitoring picture debugging, etc., according to the configuration information, according to different type of signal, range, use a variety of signal source to test I/O channels one by one and record test data, the imperfect place.This system according to ECS- 700 convenient configuration and strong control function, to optimize control system structure, reliable control, easy operation, convenient maintenance and overhaul of the ultimate goal, further implement the "less people manned and unmanned on duty" hydropower station.
