Embodiment
[0049] Taking Yushu City Power Supply Company as an example, the intelligent management software for electric heating current limiting control conducts intelligent analysis and calculation based on historical data such as weather forecasts, user usage patterns, and power load changes in the station area, and establishes N sets (N is a natural number) for each user room. ) in advance of the heating duration and time point scheme model, and determine the best preheating scheme with reference to the outdoor temperature and the current change of the station area. On the premise of ensuring the user's heating comfort, the heating power of the electric heating building has been successfully reduced by 50%.
[0050] 1. The intelligent processing method of the system when the heating fails:
[0051] ① When the heating plan is executed as a whole, the Internet of Things cloud platform 2 detects an overcurrent phenomenon in the power consumption of the station area, and it will automatic...

The invention discloses an electric heating current-limiting intelligent control system and a valley-shifting and peak-filling heat supply method thereof, and belongs to the technical field of electric heating. The electric heating current-limiting intelligent control system comprises a data base station, an Internet of Things cloud platform, a power line carrier repeater, a transformer area current acquisition protection device, a user current limiter and an electric heating temperature control terminal. According to the electric heating current-limiting intelligent control system and the valley-shifting and peak-filling heat supply method thereof, the problem that clean electric heating cannot be rapidly developed due to the limitation of the capacity of power equipment is effectively solved, current-limiting control intelligent management is carried out by using the electric heating current-limiting intelligent control system, after 50% of electricity consumption power of an electric heating building is reduced, a user can be connected into a power distribution network in a capacity-increasing-free or small-capacity-increasing mode, large-scale popularization of electric heating is facilitated, and the progress of the project of replacing scattered coal with clean electric energy in China is accelerated; and the problem that a user cannot access due to the capacity restriction of power equipment is effectively solved.
Description
technical field [0001] The invention belongs to the technical field of electric heating, and in particular relates to an electric heating current-limiting intelligent control system and a heating method for shifting valleys and filling peaks. Background technique [0002] Replacing coal with electricity is a national public welfare project. In the field of energy conversion, the more electric heating users develop, the greater the power grid company will sell, the more beneficial it is to air pollution control, and the more significant social, ecological, and environmental benefits will be generated. [0003] For a long time, due to factors such as coal-fired heating in northern my country, smog and air pollution have occurred frequently during the winter heating period, seriously endangering the lives and health of the people. In order to respond to the national call and improve the air quality in winter, local governments at all levels are facing a key problem that needs ...
