Problems solved by technology

[0003] However, the control method of the existing gas-fired internal combustion engine combined heat and power unit is only a single control closed loop, and there is no close connection between the individual control loops, and the existing internal combustion engine combined heat and power unit directly enters into the thermal power supply after the control mode is selected. Constant power mode adjustment, there will be a large shock, including the shock of power output and heat output quality

Embodiment 1

[0039] Example 1: see figure 1 , Figure 4 shown,

[0040] The present embodiment provides a method for controlling heat and electricity for a gas-fired internal combustion engine co-generation unit, including a gas source supply unit, an engine control unit, and a generator control unit, characterized in that the control method further includes a unit state judging unit , a state detection unit, and a dynamic control unit, each of which includes:

[0041] S1: Enter the mode selection, after selecting the thermal constant electricity control mode, execute S2;

[0042] S2: Enter the unit state judging unit, judge whether the unit is currently working in a cold state or a constant heating state by electricity, and execute S21 and S22;

[0043] S21: The unit is in the state of cold machine, after passing the cold machine operation control stage program, it is judged whether the unit has the control condition of constant electricity by heat, if it is satisfied, go to S3; The u...

Abstract

The invention relates to the field of gas heat and power cogeneration units, in particular to a heat-to-electricity control method for a gas internal combustion engine heat and power cogeneration unit, and provides a brand-new control method by researching and analyzing correlation characteristics existing in the whole gas internal combustion engine heat and power cogeneration unit and combining an automatic control theory. And the combined heat and power supply unit of the gas internal combustion engine is good in economical efficiency, stable and reliable in operation under the control mode that electricity is determined by heat.

Description

technical field [0001] The invention relates to the field of gas-fired combined heat and power units, and specifically designs a control method for a gas-fired internal combustion engine combined heat and power unit to determine electricity by heat. Background technique [0002] With the continuous improvement of energy saving and environmental protection awareness, the gas-fired cogeneration unit has developed rapidly. The gas-fired cogeneration unit is a generator set with an internal combustion engine as the prime mover. The high temperature circulating water and high temperature of the unit are extracted through the heat conversion unit. The heat of the flue gas is converted into the form of heat required by the user. Determining electricity by heat means that the combined heat and power unit adjusts the combustion control and heat conversion of the unit and the amount of power generated by the generator set according to the amount of heat demand at the back end. The ut...
