1, Power Monitoring System Overview

Substation remote maintenance, safety production management, centralized management, downsizing to improve efficiency and demand in the power sector, the company launched the unattended remote monitoring system. The system image monitoring, supplemented by data monitoring, combined with a variety of alarm, is being adapted to the needs of the power sector unmanned substation. The system uses advanced MPEG4/H.264 video compression and the current power industry standard IEC104 communication protocol, to a short circuit of the substation monitoring and alarm on / off, environmental parameters, site conditions, real-time, direct understanding and grasp the situation of each substation, to respond to events that occur in a timely manner, and simple operation, maintenance and use for power sector.

3, the power monitoring system

(1) video capture some of the general analog cameras, network DVR, network video servers, network cameras.

(2) video storage part of the general three storage methods: the front-end coding equipment-based front-end storage, central storage server based on the center platform, based on the back-end monitors the computer's local storage.

(3) video transmission part of the world's most advanced compression ratio high H.264 compression algorithm, the system in addition to the TCP / IP protocol, IEC104 communication protocol, to meet network technology in power system

(4) management control part of the PM-V1.0, Luo Pute Power monitoring and management software system, client management software for centralized management and control.

(5) video display are generally two ways: centralized TV wall directly with the computer decoder split-screen display. According to the characteristics of the project monitoring points, monitoring points scattered, video display some of the best use of lower cost, more flexible computer software decoder directly after the split-screen display.

(6) combined with the technical characteristics of the security facilities, built in the substation perimeter fence, four-beam infrared detectors for protection, a power plant perimeter anti-theft alarm system.

(7) electronic map is an integral part of the monitoring system, through electronic map alarm system, can accurately identify the alarm location, and can trigger the camera to record alarm locations happening, you can also trigger the lights alarm alarm equipment etc., as a warning to the intruder.

(8) intelligent behavior analysis of the video background modeling, object segmentation, pattern recognition, and a series of analysis, moving target information extracted from the video, find events of interest, the alarm rules set by the user, automatically analyze and judge the alarm event, resulting in alarm signal, which can in many cases replace or assist human monitoring.

(9) to support front-end fire alarm, motion detection alarm, emergency button alarm, burglar alarm and other alarm functions, with video, lighting, dome preset position, the electronic map function linkage, front-end substation unattended.

 

4, power monitoring system features

(1) remote monitoring of the substation area scene, listening.

(2) monitoring substation transformers, circuit breakers and other important appearance of the equipment running state.

Appearance (3) auxiliary monitoring substation CT, PT, arrester and porcelain insulators, high voltage equipment.

(4) the auxiliary monitor the substation within other oil-filled equipment, flammable appearance of the equipment state.

(5) the auxiliary monitor the substation within the division and the state of isolation switch.

(6) monitoring substation indoor environment (the main control room, the high-pressure chamber, capacitors room, separate communications room, etc.).

(7) substation burglar monitoring, perimeter, interior, access control, alarm and security dispatched; conditions are ripe and management practices allowed under the premise should be and station fire alarm linkage.

(8) real-time monitoring the working conditions of the power supply system of the communications room.

(9) real-time monitoring of the working environment of the communications room.

(10) out of the engine room personnel management.

(11) monitoring the construction of the center, the unmanned substation equipment operation and management of the classification.

(12) In the conditions are ripe and management practices allowed under the premise, the substation end video monitoring system with integrated substation automation system or remote devices (RTU) Internet capability for remote alarm information. The monitoring center can interoperate with the SCADA system, the visualization grid scheduling and maintenance.
