to ensure the statistics and analysis of power load for production management and real-time monitoring of hazard sources It is necessary to conduct real-time online monitoring on the voltage, current, power and other parameters of the incoming and outgoing circuits in the distribution room of the project site Once the monitored parameter of the monitoring point is abnormal, it can detect and alarm in time, and relevant personnel shall take necessary measures to avoid the occurrence of safety accidents The function of automatic meter reading saves manpower and material resources The function of power trend curve can intuitively display the working state and time of each circuit It is convenient for users to find out the abnormal power consumption circuit and make rectification in time The establishment of multi-level power metering system provides the basis for energy consumption analysis
the technical conditions are applicable to the maintenance of Hongshan gymnasium and the distribution room of auxiliary training hall The supplier's products shall be of high safety and reliability, easy to expand, easy to maintain and repair The products provided by the supplier shall at least meet the technical conditions, but not limited to this, and its technical performance shall meet the requirements for data monitoring in the distribution room Data acquisition
the real-time display of data adopts the visual display mode of the main wiring diagram of the distribution box, and the disconnection and fault status of each circuit switch are visible Data analysis and processing Data query and display According to the different rights of different users, the data display function is divided into three levels: operation level, management level and decision-making level The operation layer has the functions of standby energy analysis, cumulative consumption, real-time monitoring, operation record and proportion, comparison, benchmarking analysis, etc The decision-making layer has the functions of backup energy data analysis, data deletion, database import / export, etc Permission management
the system requires a reasonable and perfect user security control mechanism, which can effectively protect the information resources in the application environment and prevent the loss, theft and damage of information Energy saving transformation and effect evaluation Parameter setting Fault judgment and alarm have the function of automatic fault judgment and audible and visual alarm Alarm types include switch failure, voltage and current overrun, communication failure of field acquisition module, communication failure with monitoring system, etc The alarm time is automatically recorded in the system database, which is convenient for users to query The staff can master the real-time operation status of the substation and distribution station at any time, find the operation fault of the substation and distribution and make corresponding treatment, improve the management efficiency of the substation and distribution, and improve the safety and reliability of the power system 2 System scheme 1) Station control management In Hongshan gymnasium maintenance and auxiliary training center project, it mainly refers to the monitoring host located in the distribution room on the first underground floor 2) The network communication layer is mainly composed of collector, Ethernet device and bus network The main function of the serial server is to monitor the field intelligent instruments; the main function of the Ethernet equipment and the bus network is to realize the data interaction between the sub station and the main station, so that the distribution system management is centralized, information-based and intelligent, improve the security, reliability and stability of the distribution system, and truly achieve the purpose of unattended 3) field equipment layer System structure diagram 3 system function real time monitoring system diagram of substation is the main monitoring screen, which mainly monitors the operation status of all circuits of substation in real time, red represents closing, green represents opening In the system diagram, you can directly see the operation parameters and status of each incoming line and outgoing line, and you can see all the conventional power parameters at the outgoing side of the transformer, such as: three-phase voltage, current, active power, reactive power, power factor, frequency, active power, etc As shown in the following figure: the primary system diagram The load exceeding limit value can be set freely under the corresponding permission Support any time electrical parameter query, with data export and report printing functions The report inquires the electrical parameters of each low-voltage circuit of the incoming and outgoing lines of the distribution room of Hongshan gymnasium maintenance and auxiliary training hall, mainly including: three-phase current, active power and active power The name of each circuit in the report is associated with the database, which is convenient for users to modify the circuit name As shown in the figure below: electricity parameter reading The accurate and reliable electric energy report forms are provided for the personnel on duty The name of each circuit in the report is associated with the database, which is convenient for users to modify the circuit name As shown in the figure below, you can print the report directly and save it to another location in Excel format As shown in the figure below: power report Red indicates normal communication and green indicates communication failure The following figure is the schematic diagram of substation communication status Communication structure diagram 4 Conclusion In today's application of power distribution facilities, the safety of power distribution of the project is very important This paper introduces the application of acrel-2000 power monitoring system in Hongshan gymnasium maintenance and auxiliary training center, which can realize the real-time monitoring of power supply and distribution circuit in the distribution room, not only can display the power status of the circuit, but also has the function of network communication, and can form electricity with serial server, computer, etc Force monitoring system The system realizes the analysis and processing of the collected data, real-time display of the operation status of each distribution circuit in the distribution room, pop-up alarm dialog box and voice prompt for the load exceeding limit, and generate various electric energy reports, analysis curves, graphs, etc., which is convenient for the remote reading, analysis and Research of electric energy The system is safe, reliable and stable in operation, and solves the power consumption for the commercial plaza project The problem provides a real and reliable basis, and obtains better enterprise benefits References: [1] principle and Application guide of digital instruments for electric power measurement, Ren Zhicheng, Zhou Zhong, China Electric Power Press [2], application of electric power monitoring system in power supply and distribution design, Gao Shihong, science and technology wind [3], application of electric power monitoring in 10kV power supply and distribution design, Yao Qiang, brief introduction to the author of science and technology world: Miao Jianmei, female, Bachelor Ankerui Electric Co., Ltd focuses on smart grid power supply and distribution
