Embodiment 1
[0030] This embodiment discloses as figure 1 A power superposition comparison system for line loss monitoring is shown, the system includes a data collector installed on the secondary side of the transformer, the data collector collects three-phase power data on the secondary side, and communicates with the electric energy meter via a wireless network The protocol uploads the three-phase power data to the main station of the power load monitoring system, and the main station of the power load monitoring system obtains the secondary side data of the user at the same time, screens the abnormal power consumption that occurs according to the power mutation, and realizes the power consumption status of the station area users real-time monitoring.
[0031] In this embodiment, the data collector is arranged on the side of the electric meter in the station area, and is used to collect three-phase power data on the secondary side. The user's secondary side data is obtained from the el...
Embodiment 2
[0039] This embodiment discloses as figure 2 A power superposition comparison method for line loss monitoring shown includes the following steps:
[0040] S1 Install an electric energy meter on the secondary side of the user data collector;
[0041] S2 uploads the collected sudden power consumption data to the load monitoring master station system;
[0042] The main station of the S3 load monitoring system collects the user's electricity load change data as a comparison database;
[0043] S4 compares the power mutation load data uploaded by the collector in real time to obtain the corresponding load coincidence rate, and draws the power superposition coincidence rate curve;
[0044] S5 displays in the form of curves and reports, screens electricity theft events and phenomena in a timely manner, and issues alarms.
[0045] This example uses the power superposition of line loss monitoring and compares the energy metering data collected by the system to conduct a unified anal...
Embodiment 3
[0048] This embodiment discloses an intelligent load monitoring system, which is composed of a line loss monitoring device (data collector) for a dedicated user and a master station of the line loss monitoring system.
[0049] The data collector in the user line loss monitoring device collects, processes and stores the current three-phase current, voltage, instantaneous active power, instantaneous active power and other values of the secondary side of the user's secondary side power consumption information, and uses RS-485 to copy Read the above values of the electric energy meter, transmit the data with wireless communication technology, and upload it to the master station of the monitoring system.
[0050] The master station of the monitoring system judges whether any user has abnormal power consumption by comparing the power mutation load curve, and realizes real-time monitoring of the user's power consumption status. Effectively monitor electricity theft, improve the s...
