The invention provides a multi-element load tracking and adjusting device for sensing the real-time operation state of electric power, wherein the device comprises a communication module, an AD sampling module, a metering loop, a main control chip and a control output module; the communication module is connected with an electric appliance and is used for obtaining a parameter signal of the electric appliance; the AD sampling module is connected with the communication module and is used for carrying out data sampling on the parameter signals; the metering loop is connected with the AD sampling module and is used for determining parameter values of the electric appliance based on sampling data sampled by the AD sampling module; the main control chip is connected with the metering loop module and is used for generating a control signal of the electric appliance based on the parameter value; and the control output module is connected with the main control chip and is used for outputting a control signal to the electric appliance through the communication module. The multi-element load tracking and adjusting device capable of sensing the real-time operation state of the electric power automatically adjusts the connected multi-element load, realizes automatic adjustment control, assists the electric power system to recover to a normal state, and has the characteristics that the response time is short, the selection is good, and the control output does not depend on remote communication.
Description
technical field [0001] The invention relates to the technical field of electric power control, in particular to a multi-element load tracking adjustment device and method for sensing the real-time operating state of electric power. Background technique [0002] At present, the contradiction between seasonal peak load growth and new energy consumption in the company's business area has become increasingly prominent, and the overall energy utilization efficiency is still low. The peak duration of the peak load of more than 95% of the maximum load in the provinces in the "Sanhua" area is only 5 to 81 hours. If the 5% peak load demand is met by building a peak-shaving power plant, but only for the peak load, the cost is too high. If the customer can adjust the load to implement demand response with the same effect, the total capital scale of related software and hardware construction, operation and maintenance and subsidies can greatly delay and save power generation and power ...
