Abstract

The invention relates to a load interruption control device for a power system. The device comprises a timer, a controller, a plurality of load control terminals, a plurality of triggers, and a plurality of comparators. Each load control terminal controls the power equipment on one power supply line of the power system, and is correspondingly equipped with one comparator and one trigger. The load control terminals are connected with the controller. The controller is connected with a first input end of each trigger through the timer. The controller is connected with a second input end of each trigger through the corresponding comparator. The output ends of the triggers are connected with the controller. The controller receives load interruption information issued by a supply station, calculates interruption duration corresponding to each load control terminal and response capacity corresponding to each load control terminal, and makes each load control terminal perform an interruption operation through the timer, the triggers and the comparators according to the interruption duration and the response capacity.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an interrupt load control device of a power system. Background technique [0002] The demand response of the power system refers to guiding users to change the inherent power consumption mode through price or incentive subsidies during the period of shortage of power supply and demand, which can effectively improve the economy and reliability of power system operation. In the power market environment with tight supply and demand, it is an effective means of temporary peak shaving to carry out demand response in the form of incentive subsidies. [0003] Interruption load is the most widely applied form of incentive demand response, and has been widely implemented among industrial and commercial users in most regions. Large users or load integrators sign interruptible load contracts with power companies. During peak hours or emergencies, users complete the scheduled time an...
