As the "core unit" of power supply for power users, the distribution station area is also the "center" of low-voltage power control, and the operation status of the distribution station area directly determines whether the power users can "use electricity and use it well".
At present, there are a series of problems in the station area of China's distribution network distribution station area. For example, the control cabinet equipment is outdated, the metering device has a single function, the management is chaotic, and the load is difficult to control effectively.
With the vigorous development of the State Grid, the backbone grid and power grids at all levels are becoming more and more perfect, and the construction of power grids is gradually developing towards intelligence, focusing on the improvement of power distribution and power consumption. The distribution station is the last checkpoint between the power grid and the user, and in order to adapt to the increasing demand for electric energy, the distribution station needs to be intelligently transformed.
With the continuous development of the power industry, more and more attention has been paid to the transformation of the distribution station area, and the construction of the intelligent distribution station system is the key. The safety and stability of the intelligent distribution area is to ensure the quality and power supply capacity of the rural power grid, therefore, to adapt to the intelligent development of the rural power grid, is to meet the needs of the development of modern agriculture.
As a world-class enterprise in the field of intelligent electricity consumption and energy management in China, CET has always kept in mind the mission of "creating more reliable, safer, more energy-saving and more environmentally friendly power generation, transformation and power consumption systems for customers" since its establishment in 1993.
The CET distribution station area panoramic intelligent integrated monitoring system solution integrates the intelligent IoT system, and through the topology identification of the station area, the whole [GF]2FAF[GF][GF]The operation of power distribution facilities [GF]2F8F[GF] is perceived.
Upload the data of column transformer, box transformer and distribution room to the [GF]2F84[GF] transformer platform to realize real-time collection, storage and remote real-time alarm and monitoring of electrical parameters, environmental parameters and other data, and at the same time monitor and statistically analyze and manage the power consumption and utilization status of the item [GF]2F8F[GF]**. The platform system has the function of operation and maintenance business management, which can realize the linkage of online monitoring, offline inspection and equipment maintenance business in the station area, promote the consumption of new energy, and help build a smart station area and a new power system.
What are the functions of the panoramic intelligent integrated monitoring system in the CET distribution station area?
1.Active management of the station area
Through the information management of the low-voltage distribution station area, the real-time perception of the equipment operation [GF]2F8F[GF] in the station area, and the management status of the low-voltage distribution [GF]2F79[GF] is improved from "passive management" to "active management", which improves the reliability of power supply and the satisfaction of customers[GF]2F3E[GF].
2.Panoramic topology of the station area
Based on the dynamic topology function of the intelligent circuit breaker [gf]2f83[gf], it can effectively confirm the relationship between station, line, [gf]2f3e[gf], transformer and end.
3.Precise fault location
Identification of topological relationships in the station area, reducing the amount of [gf]2f08[gf][gf]2f2f[gf] troubleshooting [gf]2f3e[gf]variable relationship, accurately locating fault points, reducing the amount of troubleshooting[gf]2f2f[gf], and saving [gf]2f08[gf][gf]2f12[gf] costs. The housekeeper of the station area can grasp the status of the [gf]2f64[gf]2f8f[gf] power safety operation in the station area anytime and anywhere, and mobile portable operation and maintenance.
4.Distributed protection of the station area
JP cabinet inlet, outlet, sub [GF] 2F40 [ GF] box, meter box into [GF] 2F8F [ GF] distributed protection configuration, and the upper and lower protection values cooperate with each other; When the circuit has a [gf]2f63[gf] fault, the fault circuit is tripped by grade to avoid skipping tripping.
5.Fine loss line loss management
Collect the data of four levels of station area incoming line, sub-[gf]2f40[ gf] outgoing line, meter box incoming line, [gf]2f64[ gf][gf]2f3e[ gf] electric energy meter, combined with the distribution [gf]2f79[gf] topology, realize the time-sharing statistics of [gf]2f0a[gf] power, line loss and line loss rate of each node, and [gf]2f47[gf] statistics and [gf]2f49[gf] statistics, respectively, calculate the bus loss of the outlet area, Segmented line loss, so as to achieve fine management of line loss in the station area.
6.Power quality monitoring in the Taiwan area
Real-time monitoring and analysis of power quality in the Taiwan area, and timely [gf]2f8f[gf][gf]2f32[gf] pre-detection of abnormalities to ensure the reliability of system power supply.
7.Distributed Energy Management
Through the monitoring of the switching status, energy information, and operation [GF]2F8F[GF] status of charging piles, photovoltaic inverters, energy storage PCS, etc., the distributed photovoltaic input [GF]2F8F[GF] management is carried out through distributed photovoltaic switches, and the [GF]2F12[GF] [GF] is used to realize the orderly [GF]2F64[GF] of the station area. Electricity and energy synergy[gf]2f83[gf]governance, improve the comprehensive energy coordination and control [gf]2f54[gf]level in the Taiwan area.
The power equipment in the distribution station area is integrated and intelligent, forming a comprehensive software and hardware integration of the integrated solution, realizing visualization, information management, safety control, and optimizing power efficiency, which can not only improve power quality, significantly reduce line loss, improve power supply reliability, and greatly improve the level of power management, but also comprehensively solve the problems of low voltage qualification rate, low power supply reliability, large loss, low management level, low management level, and insufficient management personnel in the distribution station area, and realize no maintenance, Less maintenance, less maintenance, no maintenance, with excellent economic and social benefits.
