Application Design Of Intelligent Power Distribution System In An Office Building

Due to the lack of effective protection,condition monitoring and remote management mechanism in traditional low-voltage distribution system,the continuity of power supply and operation stability of equipment in the field power supply and distribution system are affected,and there are security risks such as over tripping,difficulty in locating fault points,etc.At the same time,the system lacks historical record and storage function for low-voltage distribution data,which is not conducive to the supervision of low-voltage distribution.In this paper,with the background of an office building intelligent distribution system transformation project,aiming at the problems existing in the traditional distribution system,using the intelligent system supported by new digital technology,the office building intelligent low-voltage distribution system is designed and studied.Firstly,in view of the current situation that the low-voltage distribution system is lack of digital protection,the protection depends on the physical characteristics of the equipment itself,and the strong and weak current systems are various and intersected,the current technical status and development trend of the intelligent distribution system are analyzed comprehensively.The new intelligent distribution terminal and the intelligent distribution system monitoring center are adopted to monitor the power,energy consumption,electrical fire and intelligent lightning protection systems In one,the intelligent management and control of low-voltage distribution system are realized.On the basis of the above demand analysis,the scheme of intelligent distribution system is determined.The organization management mode of centralized management and decentralized control and the distributed network structure are adopted.The intelligent distribution terminal is used instead of the original multi-functional instrument.The intelligent lightning protection module is embedded in the intelligent distribution system,and the system is managed uniformly through the monitoring center.The system has open communication protocol,data interface to upload information and the ability to realize unified remote monitoring management.Through the combination of 485 protocol and network layer,the site side and monitoring center are combined in real time to achieve real-time monitoring,control and management of low-voltage distribution system,which effectively solves the defect of traditional low-voltage distribution system lacking digital management and control.Finally,the low-voltage distribution system diagram and network diagram of the office building are designed in detail.
