Distribution system consists of what important parts, they play an important role in the distribution network automation technology

The distribution automation system includes the distribution grid frame, the communication system and the distribution master station. Breakdown: Distribution automation system (DAS) is an automation system that enables distribution companies to monitor, coordinate and operate distribution equipment in a real-time manner from a remote location; its contents include several parts, including distribution network data acquisition and monitoring (SCADA system), distribution geographic information system (GIS) and demand-side management (DSM). Power automation according to functional categories are: 1, scheduling automation: divided into the national transfer, provincial transfer, local transfer and county transfer. Used for substations and power stations for power generation and transmission scheduling command, automated management; 2, substation integrated automation: 500KV0KV0KVKV level substations in situ monitoring and control, and data transmission scheduling automation system; 3, distribution network automation: urban 10KV system of distribution network monitoring, control of automated management, optimization of the urban distribution network structure, rational and efficient Electricity management, accident and fault timely pre-treatment; 4, distribution automation; for factories and buildings and other end-users of power distribution equipment automation management, improve the reliability of the distribution system, for the realization of the accident in advance notice, improve work efficiency, and achieve the goal of economic operation. The following is a combination of the U.S. Swell's distribution automation system solutions, explaining the principles and applications of power distribution automation. With the continuous development of the power network, the continuous growth of the power load, a variety of new types of loads continue to emerge, the user is more concerned about the power quality problem, while energy saving and emission reduction has also put forward more stringent requirements. Users need more effective power monitoring and management solutions to cope with the challenges brought by the above changes, in order to realize the continuous reliable, efficient and low-consumption operation of the power distribution system. ZEpower power monitoring system is a complete power monitoring and management solution provided by Swire Electric according to users' power management needs to realize the optimal management of electrical equipment and power system operation.ZEpower power monitoring system adopts modern communication technology and computer technology to realize various analysis and management functions of the power distribution system, to improve the efficiency of the management of the distribution system, and to guarantee the reliable and safe operation of the distribution system, which helps users to realize the reliable and safe operation of the distribution system. It improves the efficiency of power distribution system management, guarantees the reliable and safe operation of the power distribution system, and helps users realize the goal of power consumption reduction, thus creating value for users. Power monitoring system is playing an important role in electric power system, municipal health care, intelligent building, petrochemical, metallurgy, light industry, public **** transportation, water treatment and other fields. Multi-power supply system and multiple transformer distribution system design in the bus segmentation and contact, are by using the switch to perform. There are many ways to do this, not just in removing faulty lines. Sometimes for equipment maintenance, sometimes for backup power input, sometimes to regulate the line load . . etc. Reasonable distribution network frame is the basis for the implementation of distribution automation, distribution network frame planning is the first step in the implementation of distribution automation. Distribution network frame planning should follow the following principles: (1) follow the relevant standards, combined with the actual local power grid; (2) the main line should be looped, open operation, conductors and equipment should meet the requirements of load transfer; (3) the main line should be divided into 3~5 sections, and install sectional switches, the sections mainly consider the load density, the nature of the load and the length of the line; (4) the distribution equipment itself is reliable, with certain capacity margins, and with remote control, and with the ability to control the line load. (4) The power distribution equipment is reliable, has a certain capacity margin, and has remote control and intelligent functions.
