    real time data display of important circuit, self definition of circuit name;    real time display of working status of various intelligent instruments;    drawing distribution diagram according to actual distribution structure; important power parameters, current and voltage curve display of important circuit;                                      General technical specifications for data acquisition and monitoring system of regional power grid (gb2887) technical requirements for calculation station (GB / 50198-94) engineering technical specifications for monitoring system (DL / T 698.31-2010) part 3.1: technical specifications for electric energy information acquisition terminals - General requirements (DL / T 698.35-2010) Part 3-5: Technical Specification for electric energy information acquisition terminal - special requirements for low voltage centralized meter reading terminal DL / T 698.41-2010 Part 4-1: communication protocol - communication between master station and electric energy information acquisition terminal DL / T 698.42-2010 Part 4-2: communication protocol - concentrator downlink communication protocol DL / T / 814-2013 functional specification for distribution automation system 3.2 System architecture design    in view of the scale and nature of the building of Shanghai Xichuan seal Co., Ltd and the nature of the joint development of subsequent projects, the system Department of ankerui Electric Co., Ltd designs the building of the intelligent power distribution system of the building according to the user's needs and experience in projects of the same nature: all monitoring points of Shanghai Xichuan seal Co., Ltd Intelligent power instruments have been installed, and all adopt standard Modbus RTU protocol The field installed intelligent instruments are connected by hand through shielded twisted pair, and the data bus is directly laid to the duty room of the substation where the host machine is located The data bus transmits the data to the system host through the protocol conversion isolator System diagram 1 Figure 14 System function: the upper computer software uses the acrel-3000 intelligent power management system, which configures the equipment, database variables, interface design, etc through the software, the upper computer software monitoring and power management functions are completed 4.1 functional features: acrel-3000 intelligent power management system adopts full Chinese interface, which is simple and convenient for operation and stable and reliable for operation Click the corresponding shortcut button to enter the corresponding system function module; the system has a system diagram display, simulation diagram display and network structure diagram display; the system has a friendly human-computer interface, intuitive display data, convenient for users to consult 4.2 software function: 4.2.1 communication diagram                     Through the change of interface module color to reflect the operation status of each monitoring point of the whole system The interface is shown in Figure 2 Figure 2 communication diagram 4.2.2 monitoring details                      Through the display of real-time data, it can directly reflect the operation data of each monitoring loop of the project, which is convenient for the managers to understand the real-time operation status of the system The interface is shown in Figure 3 Figure 3 monitoring detail 4.2.3 parameter reading                          The main data include: three-phase voltage, three-phase current, electric energy, active power, reactive power, power compensation factor, frequency The interface is as shown in Figure 4 Parameter meter reading 4.2.4 electric energy report                             The interface is shown in Figure 5 Figure 5 electric energy report 5 Conclusion                        At present, it is mainly through the installation of intelligent instruments in the power supply and distribution system of industrial buildings, i.e the inlet and outlet nodes of the substation, and the use of computer network integration technology to provide customers with remote meter reading, data storage, data processing and other services, so as to help customers grasp the real-time energy use of the building and realize the intelligent management of the building energy Shanghai Xichuan seal Co., Ltd intelligent power management system realizes the real-time collection, storage, display and export of power distribution system data The intelligent instruments are installed in the important nodes of the distribution system, thus the real-time data monitoring system of the distribution system At the same time of system design, installation and debugging, it also combs and checks all parameters of distribution system in detail; through checking all power parameters on site, it can understand the operation status of distribution system The system realizes the analysis and processing of the collected data, real-time display of the owner's power utilization status of each distribution circuit, and generate various power reports The installation of the system is convenient for the collection of various power parameters Through the analysis and research of data, the management party formulates the corresponding production process adjustment plan The operation of the system is safe, reliable and stable It also provides a real and reliable basis for the end-users of the distribution system to solve the problem that the specific power consumption of each distribution circuit is unknown, and for the later maintenance of the power system and the formulation of reasonable property services Reference
