The distribution automation system includes the distribution network frame, communication system and distribution network main station.
Decomposition;
Distribution Automation System (DAS) is an automation system that enables distribution enterprises to monitor, coordinate and operate distribution equipment in real-time from a remote location; its content It includes distribution network data collection and monitoring (SCADA system), distribution geographic information system (GIS) and demand side management (DSM).
Power automation is divided according to functional categories:
1. Dispatch automation: divided into national dispatch, provincial dispatch, local dispatch and county dispatch. It is used for power generation and transmission of substations and power stations. Carry out dispatching command and realize automated management;
2. Comprehensive automation of substations: on-site monitoring and control of 500KV0KV0KVKV grade substations, and transmit data to the dispatching automation system;
3. Distribution network automation: automatic management of monitoring and control of the distribution network of the urban 10KV system, optimizing the urban distribution network structure, reasonable and efficient power management, timely prevention of accidents and timely handling of faults;
4. Distribution Electrical automation; for the automated management of power distribution equipment for end users such as factories and buildings, it can improve the reliability of power distribution system operation, predict accidents in advance, improve work efficiency, and achieve the goal of economic operation. The following is combined with the American Swale System solutions for distribution automation, explaining the principles and applications of distribution automation.
With the continuous development of power networks, the continuous growth of electricity loads, and the emergence of various new loads, users are paying more attention to power quality issues and have put forward more stringent requirements for energy conservation and emission reduction. Users need more effective power monitoring and management solutions to cope with the challenges brought by the above changes to achieve continued reliable, efficient and low-consumption operation of the power distribution system.
The power monitoring system is a complete power monitoring and management solution provided by Swell Electric Company to users based on their power management needs to achieve optimal management of the operation of electrical equipment and power systems. ZEpower power monitoring system uses modern communication technology and computer technology to realize various analysis and management functions of the power distribution system, improve the efficiency of power distribution system management, ensure the reliable and safe operation of the power distribution system, and help users achieve the goal of reducing power consumption. Thereby creating value for users.
Power monitoring systems are playing an important role in power systems, municipal medical care, intelligent buildings, petrochemicals, metallurgy, light industry, public transportation, water treatment and other fields. Bus segmentation and connection in the design of multi-power supply systems and multi-transformer power distribution systems are all performed by switches. There are many ways, not just removing faulty lines. Sometimes it is for equipment maintenance, sometimes it is for backup power supply, sometimes it is for line load adjustment, etc. A reasonable distribution network frame is the basis for implementing distribution automation, and distribution network frame planning is the first step in implementing distribution automation.
Distribution network frame planning should follow the following principles:
(1) Follow relevant standards and combine with the actual situation of the local power grid;
(2) The main line should adopt Ring network wiring, open operation, wires and equipment should meet the requirements of load transfer;
(3) The main line should be divided into 3 to 5 sections, and section switches should be installed. The load should be mainly considered in sectioning. Density, load properties and line length;
(4) The power distribution equipment itself is reliable, has a certain capacity margin, and has remote control and intelligent functions.
