Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural view of a gas engine for power generation. The gas engine for electricity generation includes gas valve, blender, booster, air throttle and gas engine body for electricity generation, the output of gas valve with the input of blender is connected, the output of blender with the input of booster is connected, the output of booster with the input of air throttle is connected, the output of air throttle with the gas engine body for electricity generation is connected.
Specifically, the mixer, the supercharger, and the throttle valve may be provided in plurality. As shown in fig. 1, two branches may be provided behind the gas valve and in front of the gas engine body for power generation, each branch includes a mixer, a supercharger and a throttle, and the specific working processes of the mixer, the supercharger and the throttle in each branch are similar. For convenience of description, the embodiment of the present invention is illustrated by taking one of the branches as an example.
In practical application, low-pressure fuel gas enters the gas engine for power generation after being controlled by the fuel gas valve, flows through the mixer and is mixed with fresh air through the mixer to form mixed gas, the mixed gas flows through the supercharger and is supercharged through the supercharger, and then flows through the throttle valve and finally enters the gas engine cylinder for power generation through the control of the throttle valve.
The power generation gas engine generally adopts a technical route of premixing before pressurization, a supercharger is used for compressing the mixed gas to improve the pressure of the mixed gas, a throttle valve is used for controlling the intake flow of the mixed gas entering a cylinder of the power generation gas engine according to the calculation result of a throttle formula, and the throttle formula can calculate the intake flow of the mixed gas according to the opening degree of the throttle valve, the pressure of the air before the throttle valve and the pressure of the air after the throttle valve. When the loads of the gas engines for power generation are different, the opening degree of the throttle valve is also different in order to control the flow rate of the intake air of the mixture into the cylinders of the gas engines for power generation. When the gas engine for power generation is in a high-load state, the front pressure and the rear pressure of the throttle valve are approximately equal, the throttle valve is located at the point close to a throttling area and a non-throttling area, the small change of the opening degree of the throttle valve can cause large change of the intake flow of the mixed gas, namely the instability of the output power and the rotating speed of the gas engine for power generation can be easily caused by directly controlling the opening degree of the throttle valve through rotating speed PID closed-loop control.
The throttle region is a region in which a ratio of the throttle rear air pressure to the throttle front air pressure is less than or equal to a predetermined value, for example, the predetermined value may be 0.95. When the throttle valve is in the throttle area, the relationship between the opening degree of the throttle valve and the intake air flow rate of the mixture satisfies the requirement of the throttle formula, i.e., the intake air flow rate of the mixture is controlled by the opening degree of the throttle valve. The non-throttle region is a region in which the ratio of the throttle rear air pressure to the throttle front air pressure is greater than a predetermined value, for example, the predetermined value may be 0.95. When the throttle valve is in a non-throttle area, the relationship between the opening degree of the throttle valve and the intake air flow of the mixed gas is not applicable to the throttle formula any more, namely the intake air flow of the mixed gas is not controlled by the opening degree of the throttle valve, and at the moment, the small change of the opening degree of the throttle valve and the ratio of the rear air pressure of the throttle valve to the front air pressure of the throttle valve can cause the large change of the intake air flow of the mixed gas.
In addition, when the gas engine for power generation is in a high-load dump state, the opening degree of the throttle valve is reduced, the supercharger continues to be supercharged due to inertia, so that the pressure between the throttle valve and the supercharger is increased excessively to cause surging of the supercharger, and the output power and the rotating speed of the gas engine for power generation are unstable, and the supercharger is damaged.
Fig. 2 is a schematic configuration diagram of a gas engine for power generation provided with an intake bypass valve. The gas engine for power generation still includes the bypass valve that admits air on the basis of figure 1, the input of bypass valve that admits air with the output of booster is connected, the input of booster with bypass valve's output is connected admits air.
In practical applications, due to the provision of the intake bypass valve, the air-fuel mixture between the supercharger and the throttle valve can be returned to between the supercharger and the mixer by the control of the intake bypass valve, based on the operation of the gas engine for power generation shown in fig. 1.
In order to solve the problem that the output power and the rotating speed of the gas engine for power generation may be unstable when the gas engine for power generation is in a high-load state, in the embodiment, an intake bypass valve is added on the basis of the gas engine for power generation shown in fig. 1, an input end of the intake bypass valve is connected with an output end of the supercharger, and an input end of the supercharger is connected with an output end of the intake bypass valve. According to the embodiment of the invention, the working parameters of the gas engine for power generation are obtained, whether the gas engine for power generation is in a high-load state or not is determined, and then the opening degree of the air inlet bypass valve is adjusted, so that the stability of the output power and the rotation speed of the gas engine for power generation can be effectively controlled when the gas engine for power generation is in the high-load state.
Fig. 3 is a schematic flow chart of a gas control method for power generation according to an embodiment of the present invention. The execution subject of the method in the embodiment of the invention can be a gas engine for power generation, and specifically can be an ECU in the gas engine for power generation. As shown in fig. 3, the method in this embodiment may include:
301, obtaining working parameters of the gas engine for power generation, wherein the working parameters include at least one of the following: the air pressure of the front air of the throttle valve and the air pressure of the rear air of the throttle valve.
In this embodiment, the throttle forward air pressure is an air pressure between the supercharger and the throttle, and the throttle backward air pressure is an air pressure between the throttle and the gas engine body for power generation. The throttle forward air pressure and the throttle rearward air pressure may be obtained by pressure sensors. The acquired air pressure of the front air throttle and the acquired air pressure of the rear air throttle are the air pressure of the front air throttle and the air pressure of the rear air throttle at the same moment.
And 302, judging whether the gas engine for power generation is in a high-load state or not according to the working parameters of the gas engine for power generation.
In the present embodiment, the high load state may be specified by a user, for example, when the full load is 2000Nm, the high load state may be specified as 1500N · m or more, and the high load state may be determined by the difference between the throttle forward air pressure and the throttle rearward air pressure. When the gas engine for power generation is in a high-load state, the intake flow rate of the air-fuel mixture flowing through the throttle valve is unstable, and the instability of the output power and the rotation speed of the gas engine for power generation is easily caused by directly controlling the opening degree of the throttle valve through the rotation speed PID closed-loop control.
And 303, if the gas engine for power generation is in a high-load state, adjusting the opening of the air inlet bypass valve.
In this embodiment, the intake bypass valve may be a butterfly valve whose default natural opening is not 0, that is, a butterfly valve having a certain opening in a natural state, similar to a throttle valve of a vehicle gas engine, for example, a butterfly valve whose default natural opening is 10%. The intake air flow rate of the mixture entering the gas engine for power generation is influenced by adjusting the opening degree of the intake bypass valve. When the gas engine for power generation is in a high-load state, the output power of the gas engine for power generation needs to be reduced, the reduction of the intake flow of the mixed gas flowing through the throttle valve and entering the gas engine for power generation can be realized by increasing the opening degree of the intake bypass valve, and the stability of the rotating speed of the gas engine for power generation under the power generation working condition is further controlled.
In addition, the auxiliary adjusting function under other states can be realized through the air inlet bypass valve, for example, when the gas engine for power generation is in a high-load sudden unloading state, the opening degree of the air inlet bypass valve is set to be fully opened to realize rapid pressure relief, so that the surge of a supercharger is prevented, and the stability of the rotating speed of the power generation working condition of the gas engine for power generation is controlled; when the output power of the gas engine for power generation needs to be increased in a proper amount, the increase of the air intake flow of the mixed gas flowing through the throttle valve and entering the gas engine for power generation is realized by reducing the opening of the air intake bypass valve until the air intake bypass valve is closed, and the stability of the rotating speed of the gas engine for power generation under the power generation working condition is further controlled.
In the gas engine control method for power generation according to the embodiment, the operating parameters of the gas engine for power generation are acquired, and the operating parameters include at least one of the following: and judging whether the gas machine for power generation is in a high-load state or not according to the working parameters of the gas machine for power generation, if so, adjusting the opening of the air inlet bypass valve, and controlling the stability of the output power and the rotating speed of the gas machine for power generation when the gas machine for power generation is in the high-load state.

In this embodiment, the throttle forward air pressure and the throttle rearward air pressure are the throttle forward air pressure and the throttle rearward air pressure at the same time.
In the gas control method for power generation provided in this embodiment, the difference between the air pressure before the throttle valve and the air pressure after the throttle valve is calculated, and whether the gas machine for power generation is in the high-load state is determined according to the difference and the air pressure after the throttle valve, so that whether the gas machine for power generation is in the high-load state can be accurately determined in real time.

In this embodiment, the first preset threshold and the second preset threshold may be set according to a working condition of the gas engine for power generation.
In the gas engine control method for power generation provided in this embodiment, it is determined whether the gas engine for power generation is in a high load state by determining whether the rear air pressure of the throttle valve is greater than or equal to a first preset threshold and whether the difference value is less than or equal to a second preset threshold, and it is able to accurately determine whether the gas engine for power generation is in the high load state by comparing with the preset threshold.

For example, if the acquired throttle forward air pressure is 300kPa and the acquired throttle rear air pressure is 280kPa, the difference between the throttle forward air pressure and the throttle rear air pressure is calculated to be 20 kPa.
In this embodiment, the first threshold and the second threshold may be set according to a working condition of the gas engine for power generation, for example, if the first preset threshold is set to 260kPa, and the second preset threshold is set to 25kPa, it is determined whether the air pressure after the throttle valve is greater than or equal to 260kPa, and whether the difference is less than or equal to 25 kPa.
And step 404, if the air pressure behind the throttle valve is greater than or equal to a first preset threshold value and the difference value is less than or equal to a second preset threshold value, determining that the gas engine for power generation is in a high-load state.
In the present embodiment, for example, when the throttle back air pressure is equal to or higher than 260kPa and the difference is equal to or lower than 25kPa, it is determined that the gas engine for power generation is in the high load state, and it is possible to accurately determine whether the gas engine for power generation is in the high load state.
And 405, if the gas engine for power generation is in a high-load state, acquiring a target rotating speed of a power generation working condition of the gas engine for power generation and an actual rotating speed of the gas engine for power generation, performing rotating speed PID closed-loop control according to the target rotating speed of the power generation working condition and the actual rotating speed of the gas engine for power generation, and determining the required opening degree of the air inlet bypass valve through the rotating speed PID closed-loop control.
In this embodiment, the target rotation speed of the power generation condition is a required rotation speed of the power generation condition of the gas turbine for power generation, for example, 1500rpm or 1800 rpm. The actual rotating speed of the gas engine for power generation is the real-time rotating speed of the gas engine for power generation and can be obtained through a rotating speed sensor. The rotating speed PID closed-loop control mode may be a rotating speed PID closed-loop control mode that directly outputs the required opening of the intake bypass valve, or a rotating speed PID closed-loop control mode that outputs the required torque, or outputs a required opening of the intake bypass valve through a conversion relationship between the required torque and the required opening of the intake bypass valve, or outputs a required parameter related to the required opening of the intake bypass valve through a rotating speed PID closed-loop control mode, and the required opening of the intake bypass valve is output through a conversion relationship between the required parameter and the required opening of the intake bypass valve, which is not limited herein. The required opening degree of the intake bypass valve can be accurately determined so as to accurately control the opening degree of the intake bypass valve in real time.
And 406, determining a driving duty ratio according to the required opening of the air intake bypass valve, and adjusting the opening of the air intake bypass valve according to the driving duty ratio.
In this embodiment, the ECU may control the intake bypass valve by pwm (Pulse Width Modulation) signal, the driving duty may be a duty of the pwm signal, and the opening degree of the intake bypass valve may be adjusted by adjusting the duty of the pwm signal. The driving duty ratio is a proportion of the power-on time to the total time in one pulse cycle, and specifically, the driving duty ratio may be a percentage of the time that the controlled circuit is turned on to the whole circuit working period. For example, if the required opening degree of the intake bypass valve is determined to be 60%, the drive duty is determined to be 50% based on the required opening degree of the intake bypass valve of 60%, and the opening degree of the intake bypass valve is adjusted based on the drive duty of 50%.
And 407, acquiring the rear air inlet temperature of the throttle valve when the gas engine for power generation enters a high-load state, and determining the required opening degree of the throttle valve according to the rear air inlet temperature of the throttle valve.
Specifically, according to the air intake temperature behind the throttle valve, the required opening degree of the throttle valve is determined by inquiring a preset temperature-throttle valve required opening degree curve.
In this embodiment, the throttle rear intake air temperature may be obtained by a temperature sensor, which is not limited herein. The preset temperature-throttle demand opening curve can be calibrated according to the working condition of the gas engine for power generation, the preset temperature-throttle demand opening curve is a one-dimensional array, namely X is input, and corresponding output Y is obtained, for example, the inlet air temperature behind the throttle is 30 ℃, namely the input is 30 ℃, and the corresponding output is 80% by inquiring the preset temperature-throttle demand opening curve, namely the required opening of the throttle is 80% when the inlet air temperature behind the throttle is 30 ℃.
And step 408, fixing the opening degree of the throttle valve according to the required opening degree of the throttle valve until the gas engine for power generation exits from a high-load state.
And when the throttle valve is not in a high-load state, carrying out rotating speed PID closed-loop control through the target rotating speed of the generating working condition of the gas engine for power generation and the actual rotating speed of the gas engine for power generation, and determining the required opening degree of the throttle valve through the rotating speed PID closed-loop control. The rotating speed PID closed-loop control mode can be that the rotating speed PID closed-loop control directly outputs the required opening of the throttle valve or the rotating speed PID closed-loop control outputs the required torque, the required opening of the throttle valve is output through the conversion relation between the required torque and the required opening of the throttle valve or the rotating speed PID closed-loop control outputs the required parameter related to the required opening of the throttle valve, the required opening of the throttle valve is output through the conversion relation between the required parameter and the required opening of the throttle valve, limitation is not made, and the required opening of the throttle valve can be accurately determined so as to meet the change of the power generation load.
It is understood that the order of the above steps can be adjusted by those skilled in the art according to actual needs, for example, the steps 407 and 408 can be performed before the steps 405 and 406, or performed simultaneously.
In this embodiment, the third preset threshold, the fourth preset threshold, and the fifth preset threshold may be set according to a working condition of the gas engine for power generation, for example, the third preset threshold is set to 400kPa, the fourth preset threshold is set to 2000rpm, and the fifth preset threshold is set to 350kPa, it is determined whether the pressure of the air in front of the throttle valve is greater than or equal to 400kPa, the actual rotation speed of the gas engine for power generation is greater than 2000rpm, and whether the difference is greater than or equal to 350 kPa.
And step 410, if the air pressure before the throttle valve is greater than or equal to a third preset threshold, the actual rotating speed of the gas engine for power generation is greater than a fourth preset threshold, and the difference value is greater than or equal to a fifth preset threshold, determining that the gas engine for power generation is in a high-load sudden unloading state.
And if the air pressure before the throttle valve is not more than or equal to a third preset threshold value, and/or the actual rotating speed of the gas engine for power generation is not more than a fourth preset threshold value, and/or the difference value is not more than or equal to a fifth preset threshold value, determining that the gas engine for power generation is not in a high-load sudden unloading state. Step 405 is then performed.
In this embodiment, the high-load sudden unloading state may be calibrated by a user, for example, the load of the gas engine for power generation may be calibrated to be suddenly unloaded from 2000N · m to 500N · m or 0 for high-load sudden unloading, and the high-load sudden unloading state may be determined by a difference between the throttle forward air pressure and the actual rotational speed of the gas engine for power generation and the throttle forward air pressure and the throttle backward air pressure. When the gas engine for power generation is in a high-load sudden unloading state, a condition of supercharger surge may occur, damage the supercharger, and cause instability of output power and rotation speed of the gas engine for power generation.
In practical applications, for example, when the throttle forward air pressure is equal to or greater than 400kPa, the actual rotational speed of the gas turbine for power generation is equal to or greater than 2000rpm, and the difference is equal to or greater than 350kPa, it is determined that the gas turbine for power generation is in a high-load dump state, and it is possible to accurately determine whether the gas turbine for power generation is in the high-load dump state.
In step 411, if the gas engine for power generation is in a high-load dump state, the opening degree of the intake bypass valve is set to be fully opened.
In this embodiment, when the gas engine for power generation is in a high-load sudden unloading state, the opening of the intake bypass valve is set to be fully opened, so as to realize rapid pressure relief between the throttle valve and the supercharger, prevent the supercharger from surging, protect the supercharger from being damaged, and control the stability of the output power and the rotation speed of the gas engine for power generation.
The gas engine control method for power generation provided in this embodiment calculates a difference between a forward air pressure of a throttle valve and a backward air pressure of the throttle valve by obtaining operating parameters of the gas engine for power generation, determines whether the gas engine for power generation is in a high-load state, fixes an opening degree of the throttle valve if the difference is positive, determines a required opening degree of an intake bypass valve by rotating speed PID closed-loop control, further determines a driving duty ratio, adjusts the opening degree of the intake bypass valve according to the driving duty ratio, determines whether the gas engine for power generation is in a high-load sudden unloading state when the gas engine for power generation is in the high-load state, sets the opening degree of the intake bypass valve to be fully open if the required opening degree is positive, can accurately determine whether the gas engine for power generation is in the high-load or high-load sudden unloading state, and when the gas engine for power generation is in the high-load, the opening of the air inlet bypass valve is accurately controlled, so that the stability of the output power and the rotating speed of the gas engine for power generation is effectively controlled in real time, and the damage of a supercharger is prevented.
