Auxiliary power monitoring system

Abstract

The invention discloses an auxiliary power monitoring system comprising a station control layer, a master control unit and a spacer layer. The station control layer comprises a DCS system server and a DCS system engineer station. The DCS system server and the DCS system engineer station are both accessed to an Ethernet. The master control unit layer comprises DPUs of a DCS system. The spacer layer comprises a protection and monitoring device which is accessed to an onsite bus. One end of each DPU is accessed to the Ethernet, and the other end is accessed to the onsite bus. The spacer layer and the DPUs of the master control unit layer are communicated directly so that communication time is shortened and timeliness of communication is ensured. The system is directly monitored via the DCS system engineer station, and an electrical engineer station is eliminated so that investment of devices is reduced, laying of cables is reduced, cost is saved, a conventional networking structure of adopting an electrical monitoring system and the DCS system to operate electrical devices simultaneously is changed, direct monitoring of the DCS system towards an auxiliary power system is realized and communication efficiency is enhanced.

Description

technical field [0001] The invention relates to an electricity monitoring system, in particular to a utility electricity monitoring system. Background technique [0002] The plant power monitoring system is a system that realizes the management, monitoring, and data storage of the plant power system. The plant power system occupies a very important position in the production and daily operation of the power plant.

Problems solved by technology

[0003] There are a lot of electrical equipment in the power plant, and the amount of information is large. During the data transmission process, it is easy to cause data congestion and system collapse. The general plant power monitoring system not only undertakes the monitoring background work of electrical equipment, but also communicates with the DCS system (distributed control system) , but also communicate with the SIS system (factory-level monitoring information system) and other external systems. There is a time difference between the information obtained by different systems, and the failure to process the information in time will cause greater risks in the operation of electrical equipment.

The general factory electricity monitoring system includes electrical engineer station and DCS system engineer station. The operating status of electrical equipment and corresponding processing, which caused repeated configuration of the electrical engineer station and the DCS system engineer station, which increased costs for the enterprise
