The system comprises an electric energy master control box, an electricity measuring device andcircuit breakers ; the electric energy master control box is used for determining historical data of a power load control system through induction current parameters in a non-contact induction intelligent terminal; the electricity measuring device comprises an electricity measuring module, a processing module and a load operation module; the circuit breakers are arranged at the power grid nodes of each region of the power distribution network, realize information interaction with the power load control system and control circuit break, and are connected with the electricity measuring devices to be provided with differential protection devices; and the power load control system obtains current parameters from the prediction model of the electric energy main control box, and starts a circuit breaker when a warning line is reached according to the working load value of the load obtained by the electricity measuring device, and disconnects the connection between the load and the power grid node. By optimizing the distribution and the number of the electricity measuring devices, accurate energy conservation and emission reduction are achieved, electricity is limited for large-power-consumption users, and the healthy development concept is promoted.

Description

technical field [0001] The invention relates to a power load control system and method combined with a power measuring device, belonging to the technical field of electrical instruments. Background technique [0002] With the advancement of technology, the data detected by electrical instruments can be effectively used for prediction and mining, which can play a very critical role in power load control. In the past, the power measurement devices were often processed after the event, and when the fault occurred, the grid response had a serious lag; the predicted value obtained through training with historical data in advance has appeared in the national grid system more and more, but in the power load. There is no relevant scheme on the control system, and there is no matching improvement plan for the power measuring device. With the emergence of measures such as energy conservation and emission reduction, and power curtailment in various places, a technical solution that co...
