Background and challenges

Distribution as the power system, transmission, change, distribution links in the most close to the user's links, and social production and life are closely related, has a very important role. Improve the distribution network power supply reliability and quality of power supply, the people live and work in peace and contentment, economic development, rich life of the important guarantee.

In recent years, for the theft of power distribution facilities have occurred, while the old equipment overload prone to overheating caused by fire, theft, fire has become the focus of power distribution production management. The comprehensive auxiliary system is put into operation, to the full range of perception of distribution network operation environment, reliable power supply for escort.

The main problems faced by the integrated auxiliary system at the present stage:

Magix integrated monitoring, auxiliary subsystem is limited, only a small amount of the deployment of video, smoke, access control and other less, unable to realize the running environment and comprehensive monitoring;

- business integration less -- "remote viewing" mostly only to realize video review, the trace the historical function, video surveillance system is still independent to the production system, not really into the distribution network management process;

- human intervention multi - video monitoring anomalies need artificially found, the linkage mechanism between multiple systems have been established, but most of them are limited to switch linkage and non linkage agreement;

- operation and maintenance difficult -- networked systems, in the face of a large number of video surveillance equipment, operation and maintenance workload is huge and hard to detect, often resulting in fault processing is not seasonable, so that greatly reduced the effect of video surveillance system.

Solution

The solution scheme of intelligent power distribution system is mainly used in the construction and improvement of the comprehensive auxiliary system of the intelligent power distribution network of the Power Grid Corp.
Integrated auxiliary system of intelligent distribution network is a set of hardware, software, network in one of the large-scale network monitoring system. In the energy industry, iVMS-9800 software platform as the core, to achieve multi-level networking and cross regional monitoring and in control center / operation and maintenance center on the front end system centralized monitoring and unified management and escort for the smart grid.

The system architecture diagram is as follows:

  Integrated auxiliary system of intelligent distribution network comprehensive use of HD, intelligent, networking, application of 3G technology, under the guidance of the principle of "standardization, integration, intelligent design, the standardization of industry products, to achieve the following functions:

L multiple video monitoring: support HD video surveillance, intelligent video surveillance, mobile video surveillance, to enhance the video quality and the level of security;

- Assist System Integration: video surveillance, environmental monitoring, security alarm, access control, intelligent control subsystem integration, each subsystem according to plan linkage;

- Visual Management: on-demand allocation of regional video inspection plans and communications with the dscada system. When switching operation or tripping accidents, dscada send remote control or remote communication signal to the video monitoring system and related preset camera;

Magix stereoscopic supervision mode: front-end, county, city level three vertical supervision, fixed network using C / s and B / S mode access, mobile network through handheld management terminal (mobile phone, tablet, etc.) Regulation;

System operation and maintenance management: management of IT infrastructure, diagnosis of video quality, bandwidth optimization and control, asset management, log management.

Program highlights

1) mobile video monitoring is used for the inspection of the whole process, the command staff can be very convenient through the audio and video to understand the situation, and on the spot to give timely correction and guidance;

2) closer integration visualization management and business process, in every time attendance after the end of the timely upload video data, the video data and work ticket, operation ticket, emergency repair single content is associated with, business processes to achieve closed-loop.
