Embodiment 2

[0088] The control method for the heating controller to control the heating power M of the carbon fiber heater set in the room is:

[0089] P(t,w 2 ) at any moment w 2 Compared with the upper load limit Q,

[0090] When w is satisfied at any time 2 ≤Q, set as case 1);

[0091] at any time w 2 When the condition of ≤Q cannot be satisfied, it is set as case 2);

[0092] For case 1):

[0093] The integrated controller follows the curve S(t, [m 3 -G(d 2 -d 3 )][1+η(h 2 -h 3 ) / h 3 ]) Control the heating power of the carbon fiber heater of the day;

[0094] For case 2):

[0095] Heating controller calculates w 2 -Q is greater than or equal to 0 start and end time t s and t f , if w 2 - The time when Q is greater than or equal to 0 corresponds to multiple time periods, then the start and end time t of the nth continuous time period is obtained sn and t fn , and then the integrated controller controls the heating power of the carbon fiber heater of the day according...

Abstract

The invention provides a control system for balancing electric load and reducing electric capacity increase. A carbon fiber heating controller, implementing power load acquisition device, power load forecasting device, and comprehensive analysis and control device are set up to predict the power load based on parameters such as power consumption within three days and temperature changes within a period of time in the future, and combine the prediction results to calculate the heating power. control to achieve cell load balance. The humidity detection device and meteorological data are set up, and the change of the heating power brought by the humidity is taken into account when the power prediction is performed, and the calculation is performed with [m‑G(d 2 -d 3 )][1+η(h 2 ‑h 3 ) / h 3 ] indicates the predicted heating consumption power, and the prediction is more accurate; when the heater is actually controlled for heating, the upper limit of the load of the entire community is considered. When the actual heating power is greater than the upper limit of the load, two methods are used to adjust to ensure the accuracy of heating At the same time, it ensures that the grid is not overloaded.

Description

technical field [0001] The invention relates to a carbon fiber electric heating system, in particular to a control system for balancing electric load and reducing electric capacity increase. Background technique [0002] With the continuous development of my country's economy and the continuous improvement of people's awareness of environmental protection, electric heating has gradually been promoted as a clean heating method. Carbon fiber electric heating has an efficiency of more than 99% in converting electrical energy into heat energy, and there is no heat transmission loss. Electric heating has a long service life, one-time investment, clean and environmentally friendly, easy to use, and can realize the temperature control of a single room at the same time, so it is favored by the majority of users. [0003] The designed electric load capacity of general users is about 10kW. Based on this power capacity design, the contradiction between power supply and demand in most ...
