Embodiment 1
[0055] like figure 1 , 2 As shown, step 200 is executed, and the equipment file module 100 reads the equipment data through the data interface, and establishes the topological diagram of the power supply logic relationship of "household - station area - 10kV line - substation", and calculates the maximum allowable load capacity of each equipment attribute. Split processing and statistical storage of the monitoring point data. At least one of monitoring point data user data, station area data and 10kV line data, wherein the user data includes voltage, current and power; the station area data includes voltage, current, power, temperature and latitude and longitude; the 10kV line data includes The voltage, current and power of the first, middle and last stages.
[0056] Step 210 is executed, and the data collection module 110 performs data collection. According to the identification of each measuring point in the topology diagram of the power supply logic relationship, the dat...
Embodiment 2
[0061] like image 3 As shown, the system is mainly composed of four major functional subsystems: power supply quality data acquisition is the basic source of platform data, which can integrate power supply quality data from multi-party distribution network power supply quality monitoring such as voltage monitoring system, harmonic monitoring system, and marketing system; Intelligently analyze the monitoring data to obtain the required power supply quality level information, including five modules: power supply quality assessment, power supply quality warning, harmonic power flow, disturbance source identification, and power supply quality trend prediction. Each module can cooperate with each other to analyze the result information Shared by other modules; the expert decision-making system provides technical support for practical applications such as power supply quality management and power supply planning for management departments. The power supply quality governance feedba...
Embodiment 3
[0088] like Figure 4 As shown, the system consists of four functional modules: data acquisition module, data storage and processing module, low-voltage intelligent diagnosis module, and expert management strategy library; the data acquisition module automatically (timingly) collects distribution network SCADA system and metering automation through the data interface. System, voltage monitoring system, energy system and other monitoring point data are classified, processed and statistically stored; the low-voltage intelligent diagnosis module conducts multi-dimensional diagnostic analysis and summarizes low-voltage characteristics according to the data classified and processed in the previous period; the expert management strategy system follows The low-voltage feature data automatically retrieves the policy library, and automatically summarizes and outputs the current low-voltage problems in the station area, the main characteristics of low-voltage, governance principles, and ...
