Abstract

The invention provides a method for evaluating the peak-shaving capacity of a heating unit, which is applied to the technical field of the peak-shaving capacity evaluation. The method comprises the following steps of: setting a first limiting condition for the field test of the minimum output capacity of the peak load regulation of the heating unit; performing a field test at a preset heating loadunder the first limiting condition to obtain a first test result; the second test result is obtained by data inquiring and calculating the relevant parameters of the heating unit; the first test result and the second test result are analyzed and calculated to obtain the peak-shaving output range of the heating unit. The invention provides a method for evaluating the peak-shaving capacity of a heating unit, which effectively evaluates the peak-shaving capacity of the heating unit.

Description

technical field [0001] The invention belongs to the technical field of peak-shaving capability evaluation, and more specifically relates to a method for evaluating the peak-shaving capability of a heating unit. Background technique [0002] The rapid development of new energy units has put forward higher and higher requirements for deep peak regulation of thermal power units. Among the thermal power units, since the heating unit supplies heat and electricity to the outside world at the same time, its thermoelectric coupling characteristics greatly increase the difficulty for the unit to participate in the peak regulation of the power grid. At present, the seasonal peak-shaving output of many heating units can only be reduced to about 70%. [0003] The in-depth peak-shaving and flexible technical transformation of heating units will inevitably involve the evaluation of the peak-shaving capacity of the unit, and the determination of its peak-shaving capacity and output range ...
