Nanjing Daquan Automation Technology Co., Ltd. Distribution Automation Solution

Distribution automation is to integrate the real-time operation of distribution network, power grid structure, equipment, users, geography and other information by using modern computer and communication technology to form a complete automation system, so as to realize the automation and informatization of distribution network operation monitoring and management, thus improving power supply quality, operation efficiency and management level, and further improving user satisfaction.

As shown in the figure, Daquan Automation can provide an overall solution for distribution automation system, including distribution master station, communication network, distribution substation and various distribution monitoring terminals (DRTU). It can realize the information collection, processing and monitoring of various distribution equipment and lines such as ring network cabinet, switching station, distribution room, lever switch, box transformer and substation transformer. Based on this, we can know the operation status of each distribution station in time, provide technical support for the safe operation of primary equipment on site, and provide basic data for many management functions such as line loss analysis, load forecasting and feeder automation, which has a positive effect on improving the operation reliability of distribution network, improving power supply quality, reducing labor intensity, shortening power outage time and narrowing power outage scope. According to different applications, it can be divided into: DA-D200 station terminal: used for real-time monitoring of various distribution equipment and line information such as small substations, switching stations, ring network cabinets and distribution rooms; It can be installed in the switchgear locally or assembled centrally. DA-F200 feed terminal: used to monitor 10kV/6kV feed switch. It can be directly hung on outdoor telephone poles (for single-wire control or double-wire control erected on the same pole) or installed in cable ring network cabinet. It can realize remote control, telemetry, remote communication, fault detection and fault discrimination, telemetry overrun detection and other functions. DA-T200 distribution transformer terminal: used for monitoring distribution transformer, which can realize automatic meter reading, power consumption monitoring, reactive power compensation, power quality analysis, load analysis, voltage qualification rate statistics, abnormal monitoring of metering equipment, abnormal monitoring of transformer and line loss analysis. DA-K200 switch controller: used for branch line monitoring and fault isolation. , which will narrow the scope of the fault and will not affect the normal operation of other users in the substation and feeder.
