Intelligent low voltage load measuring and controlling device for power distribution network

Abstract

The invention provides an intelligent low voltage load measuring and controlling device for a power distribution network. The device comprises a mutual inductor module, a data acquiring module, a microcomputer processing module, a wireless communication module and a power supply module, wherein the mutual inductor module is used for inducing voltage and current signals from a circuit system; the data acquiring module is connected with the mutual inductor module; the microcomputer processing module is connected with the data acquiring module; the power supply module is used for supplying power for the modules; and the microcomputer processing module is in wireless communication with a dispatch center through the wireless communication module. According to the device provided by the invention, as the voltage and current data at the low voltage side of a substation transformer of the circuit system is automatically monitored and acquired, and as the load distribution situation is automatically analyzed and stored according to the acquired data, the change situation of the load is actually recorded, thus, the device has the advantages of rational structure, multiple function and high reliability.

Description

technical field [0001] The invention relates to a load measurement and control device used in the electric power industry, in particular to an intelligent low-voltage load measurement and control device for a distribution network. Background technique [0002] Knowing the low-voltage load of public distribution transformers at any time is conducive to ensuring the safe operation of public distribution transformers and avoiding burning out of public distribution transformers due to overload. The existing comprehensive tester for power distribution operation can only realize automatic data collection, and manual on-site meter reading is required to extract the data, and then input the data into the main computer for record and analysis. , which seriously affects the accuracy of data statistical analysis and hinders the process of automatic management of power distribution system. At the same time, due to the large quantity and wide area of ​​distribution transformers, the ins...

The existing comprehensive tester for power distribution operation can only realize automatic data collection, and manual on-site meter reading is required to extract the data, and then input the data into the main computer for record and analysis. , thus seriously affecting the accuracy of data statistical analysis and hindering the process of automatic management of power distribution system

At the same time, due to the large quantity and wide area of ​​distribution transformers, the installation conditions are very complicated, and the operation conditions are also ever-changing. There are often severe unbalanced loads on the low-voltage side, overloaded transformers, low power factor and voltage pass rate, etc., which seriously affect the distribution facilities. The safety and economy of normal operation, etc., the existing comprehensive tester for power distribution operation has been far from meeting the actual needs of the current distribution network operation
