Demand Analysis
Power supply company distribution room distribution room has the characteristics of decentralization, changing geographic conditions, wide coverage, many users, and easy to be affected by user capacity increase and urban construction due to its large number and wide distribution. The monitoring and control of distribution rooms is of great significance for distribution automation management, line loss analysis, load forecasting and power demand management.
The traditional solution is to install monitoring settings such as ring network cabinets, switchgear cabinets, transformers, etc., as well as alarm, video and environmental monitoring systems, etc., respectively, but these systems have the following problems:
1, many devices are not networked, but only in the local monitoring and control;
2, the networking of the systems run independently of each other, the formation of monitoring "island" phenomenon, can not be effectively managed, but also can not achieve the effect of safety management.
3, the current patrol of the distribution station are recorded manually, there will be a signature, statistics, time-consuming and laborious, can not do real-time monitoring and management.
4、Multi-system coexistence not only increases the investment cost, the later maintenance cost is also greatly increased, and more than one manufacturer's equipment running at the same time, will also produce the phenomenon of tug-of-war, a waste of the owner's time and energy.
the principle of work
As the "brain" of the whole system, the auxiliary monitoring platform is responsible for storing, processing, analyzing and issuing commands to the terminal of the environment and equipment status information of the distribution room. It is also a working platform for operation and maintenance personnel, realizing remote monitoring of the overall operation status of the distribution room, danger warning and abnormality alarm. The data interaction and transmission system is the "nerve network" of the whole system, connecting the application platforms, intelligent distribution gateway, sensor devices, etc., realizing real-time data transmission, and displaying it to the relevant privileged users in the auxiliary monitoring platform of the distribution station house. Intelligent distribution gateway is the "sensory system" of the whole system, which is responsible for storing, processing and analyzing the information of each functional sub-module in the distribution room, and transmitting it to the auxiliary monitoring platform of the distribution room through standard protocols. When the preset limit value is exceeded, the intelligent distribution network will be activated to control the relevant index parameters of the distribution station room within the target range. Sensor equipment is the "hands and feet" of the whole system, realizing the collection of monitoring information in the distribution station room. Based on the actual situation of the provincial information network and terminal equipment construction in the distribution substation room, with the help of loT platform and visualization platform uniformly deployed in the information intranet, the environment class and status class collected data are stored and visualized respectively. With the help of loT platform and visualization platform uniformly deployed in the information intranet, it can respectively realize the storage of collected data such as environment class, state class, etc. and the storage of video information; the auxiliary monitoring platform of the power distribution station room obtains the relevant data information from the loT platform and the visualization platform respectively, conducts the analysis and processing, and displays the analysis result information.
