Smart energy management system

Abstract

A smart energy management system comprises a microcomputer protection device, a communication management machine, a monitoring host, a power distribution terminal encryption box and a DTU, wherein anRS485 interface of the microcomputer protection device and an RS485 interface of the communication management machine are in communicating connection by a shielded twisted pair, an Ethernet interfaceof the communication management machine and an Ethernet interface of the monitoring host are in communicating connection, the RS485 interface of the communication management machine and an RS485 interface of the power distribution terminal encryption box are in communicating connection by a shielded twisted pair, an RS232 interface of the power distribution terminal encryption box and an RS232 interface of the DTU are in communicating connection by a shielded twisted pair, the DTU is connected to an electricity bureau main station by wireless communication, and the monitoring host, the communication management machine, the microcomputer protection device, the power distribution terminal encryption box and the DTU are respectively connected to the power source. The smart energy management system can collect and display various running switch quantities, analog quantity states and power quantity parameters of the power distribution system in real time, and can completely grasp the real-time running state and historical events of the power distribution system.

Description

technical field [0001] The invention relates to a management system, in particular to a smart energy management system. Background technique [0002] In the existing 10KV circuits, the central cabinet is generally used, which can be used for line protection such as incoming and outgoing lines, and can also be used for equipment protection such as PT, main transformer backup protection, motors, capacitors, and reactors. Generally, the central cabinet microcomputer protection device will be installed. The central cabinet microcomputer protection device integrates multiple functions such as protection, measurement, monitoring, man-machine interface, communication, etc.; it is specially designed for "unitization" of switch cabinets. One device It can complete all the automation functions in the switch cabinet, simplifies the secondary design and construction of the switch cabinet, replaces various conventional relays and measuring instruments, and saves a lot of installation spa...

Problems solved by technology

However, the power bureau is still unable to collect and display the various operating switch states and power parameters of the power distribution cabinets in real time. It cannot clearly know the historical events of each cabinet, and cannot fully grasp the real-time operating status of the power transformation and distribution system. , when the cabinet fails, the power bureau cannot accurately know the cause of the fault and the specific cabinet
