Embodiment Construction

[0047] The preferred examples will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0048] figure 1 A block diagram of the basic steps of the segmental calculation method for the deep peak regulation energy consumption cost of the plasma ignition coal-fired unit provided by the present invention. figure 1 The method described in is characterized in that it comprises the following steps:

[0049] Step 1: Calculate the variable load loss cost caused by rotor low cycle fatigue loss and high temperature creep loss.

[0050]The variable load of the unit makes the thermal stress of the rotor shaft system of the unit too large, and the excessive alternating thermal stress will cause low cycle fatigue life loss and creep loss, which can lead to serious deformation and fracture of the unit body and reduce the l...

Abstract

The invention provides a method for calculating the deep peak regulation energy consumption cost of a coal-fired unit based on a plasma ignition technology. The method comprises the following steps: (1) calculating the unit depth peak regulation variable load loss cost according to the operation state difference of the plasma ignition coal-fired unit in different depth peak regulation stages; (2)calculating the plasma ignition cost of the deep peak regulation combustion-supporting stage; and (3) on the basis of considering the coal consumption characteristics, constructing the deep peak regulation energy consumption cost piecewise function of the plasma ignition coal-fired unit. The patent achievements provide a basis for economic operation of a thermal power plant adopting a plasma ignition combustion-supporting technology.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for calculating the cost of energy consumption for deep peak regulation of coal-fired units based on plasma ignition technology. Background technique [0002] Due to the randomness and intermittent nature of wind energy, large-scale wind power grid integration will increase the peak-to-valley difference in equivalent load of the system. my country's existing peak-shaving resources are insufficient, and the newly added peak-shaving tasks after wind power grid-connected are mainly undertaken by coal-fired units. Large-scale curtailment of wind power. Against the backdrop of increasingly severe wind curtailment and power cuts, the society's calls for deep peak regulation of coal-fired units are getting louder and louder. However, the deep peak regulation of coal-fired units makes the output of the units deviate from the economic operation area for a long time, and ...
