Solution for Comprehensive Auxiliary System of Intelligent Distribution Network

Project Overview

This plan fully adopts high-definition, intelligent, IoT, and 3G application technologies, and integrates with the distribution network business process under the design principles of "standardization, integration, and intelligence" to achieve visual operation and maintenance management. It is suitable for city level companies to carry out intelligent distribution network management throughout the city.

Background and Challenges

Distribution, as the closest link to users in the power system's generation, transmission, transformation, and distribution, is closely related to social production and life, and plays an extremely important role. Improving the reliability and quality of power supply in the distribution network is an important guarantee for achieving people's livelihood, economic development, and prosperity.
In recent years, theft of power distribution facilities has occurred from time to time. At the same time, overloading old equipment with electricity can easily cause fires, making theft prevention and fire prevention the focus of power distribution production management. The operation of the comprehensive auxiliary system can comprehensively perceive the operating environment of the distribution network and provide reliable power supply protection.
The main problems faced by the comprehensive auxiliary system at present are:
Lack of comprehensive monitoring - the auxiliary subsystems are limited, with only a small number of deployed video, smoke detectors, access control, etc., which cannot achieve comprehensive monitoring of the operating environment in all aspects;
Lack of business integration - "remote viewing" mostly only realizes the functions of video review and historical tracing, and the video surveillance system is still independent of the production system and has not been truly integrated into the distribution network management process;
Multiple human interventions - Abnormal situations in video surveillance points require active detection by humans. The linkage mechanism between multiple systems has gradually been established, but most of them are limited to switch linkage rather than protocol linkage;
Difficulty in operation and maintenance - After the system is connected to the internet, facing a large number of video surveillance devices, the workload of operation and maintenance is huge and the detection difficulty is high, often resulting in delayed fault handling, which greatly reduces the effectiveness of the video surveillance system.

Solution

system architecture

The solution of intelligent distribution network comprehensive auxiliary system is mainly applied to the construction and renovation of intelligent distribution network comprehensive auxiliary systems in various city companies of power grid companies.
The intelligent distribution network comprehensive auxiliary system is a large-scale networked monitoring system that integrates hardware, software, and network. With the iVMS -8800 platform software in the energy industry as the core, it realizes multi-level networking and cross regional monitoring. The front-end system can be centrally monitored and managed in the control center/operation and maintenance center to safeguard the smart grid.
The system architecture diagram is as follows:



The intelligent distribution network comprehensive auxiliary system fully adopts high-definition, intelligent, IoT, and 3G application technologies. Guided by the design principles of "standardization, integration, and intelligence", standardized industry products are used to achieve the following functions:
Diversified video surveillance: supports high-definition video surveillance, intelligent video surveillance, and mobile video surveillance, comprehensively improving video quality and security level;
Integration of auxiliary systems: realize the integration of subsystems such as video surveillance, environmental monitoring, security alarm, access control, intelligent control, etc., and link each subsystem according to the plan;
Visual operation management: Area video patrol plans can be configured as needed, and can also communicate with the DSCADA system. When switching operations or tripping accidents occur, DSCADA sends "remote control" or "remote signaling" signals to the video surveillance system, associating the corresponding camera preset positions;
Stereoscopic supervision mode: Implement vertical supervision at the front-end, county, and city levels, with fixed networks accessed through C/S and B/S methods, and mobile networks supervised through handheld management terminals (mobile phones, tablets, etc.);
System operation and maintenance management: IT infrastructure management, video quality diagnosis, bandwidth optimization and control, asset management, log management.

System Features
1) Mobile video surveillance is used for the entire inspection process, and command personnel can easily understand the on-site situation through audio and video, and provide timely correction and guidance for on-site work;
2) Closely integrate visual management and business processes, upload video data in a timely manner after each attendance, associate video data with work tickets, operation tickets, and emergency repair orders, and achieve closed-loop business processes.
