[0034] Embodiment One

[0035] Figure 1 is a flow chart of a control method of an electric boiler provided in Embodiment One of the present application. The present embodiment can be applicable to the load control of an electric boiler. The method can be executed by a control device of the electric boiler, which can be realized in the form of hardware and / or software. In a specific embodiment, the control device of the electric boiler can be configured in a control terminal. As shown in the figure, the method of the present embodiment specifically includes the following steps: Figure 1

[0036] ​S101, acquire a working parameter of an electric boiler.

[0037] The electric boiler is powered by electricity and converts electrical energy into heat energy. The working parameter includes a temperature parameter, a pressure parameter, and a liquid level parameter.

[0038] Specifically, the temperature parameter, the pressure parameter, and the liquid level parameter of the electric boiler are directly acquired from the electric boiler.

[0039] S102, determine whether the working parameter meets a preset condition.

[0040] The preset condition is a condition of the working parameter set in advance.

[0041] Specifically, it is determined whether the temperature parameter is greater than a first preset parameter, or whether the pressure parameter is greater than a second preset parameter, or whether the liquid level parameter is greater than a third preset parameter. If the temperature parameter is greater than the first preset parameter, or the pressure parameter is greater than the second preset parameter, or the liquid level parameter is greater than the third preset parameter, it is determined that the working parameter does not meet the preset condition. If the temperature parameter is less than or equal to the first preset parameter, and the pressure parameter is less than or equal to the second preset parameter, and the liquid level parameter is less than or equal to the third preset parameter, it is determined that the working parameter meets the preset condition.

[0042] The first preset parameter is a temperature value set in advance and is used to determine whether the temperature parameter meets the preset condition. The second preset parameter is a pressure value set in advance and is used to determine whether the pressure parameter meets the preset condition. The third preset parameter is a liquid level parameter set in advance and is used to determine whether the liquid level parameter meets the preset condition.

[0043] Specifically, it is determined whether the first preset parameter, the second preset parameter, and the third preset parameter, whether the temperature parameter is greater than the first preset parameter, or whether the pressure parameter is greater than the second preset parameter, or whether the liquid level parameter is greater than the third preset parameter. If the temperature parameter is greater than the first preset parameter, or the pressure parameter is greater than the second preset parameter, or the liquid level parameter is greater than the third preset parameter, it is determined that the working parameter does not meet the preset condition, and S104 is executed. If the temperature parameter is less than or equal to the first preset parameter, and the pressure parameter is less than or equal to the second preset parameter, and the liquid level parameter is less than or equal to the third preset parameter, it is determined that the working parameter meets the preset condition, and S103 is executed.

[0044] For example, if the first preset parameter is determined to be 85 degrees Celsius, the second preset parameter is determined to be 22 MPa, and the third preset parameter is determined to be 200 mm, the temperature parameter of the electric boiler is determined to be 88 degrees Celsius, the pressure parameter of the electric boiler is determined to be 30 MPa, and the liquid level parameter of the electric boiler is determined to be 220 mm, the temperature parameter 88 degrees Celsius is greater than the first preset parameter 85 degrees Celsius, the pressure parameter 30 MPa is greater than the second preset parameter 22 MPa, and the liquid level parameter 220 mm is greater than the third preset parameter 200 mm. Therefore, it is determined that the working parameters do not meet the preset conditions, and S104 is performed. If the temperature parameter of the electric boiler is determined to be 80 degrees Celsius, the pressure parameter of the electric boiler is determined to be 20 MPa, and the liquid level parameter of the electric boiler is determined to be 200 mm, the temperature parameter 80 degrees Celsius is less than or equal to the first preset parameter 85 degrees Celsius, the pressure parameter 20 MPa is less than or equal to the second preset parameter 22 MPa, and the liquid level parameter 200 mm is less than or equal to the third preset parameter 200 mm. Therefore, it is determined that the working parameters meet the preset conditions, and S103 is performed.

[0045] S103, determining a control mode of the electric boiler, and controlling the electric boiler based on the control mode.

[0046] The control mode includes a dispatch mode, a manual mode, and an on-site mode. If the dispatch mode is selected, the registers of the manual mode and the on-site mode are reset. Similarly, if the manual mode is selected, the registers of the dispatch mode and the on-site mode are reset. If the on-site mode is selected, the registers of the dispatch mode and the manual mode are reset.

[0047] Specifically, if the working parameters meet the preset conditions, the control mode of the electric boiler is determined to be the dispatch mode, the manual mode, or the on-site mode, and the electric boiler is controlled based on the determined control mode. At the same time, the manual power setting value is fed back to the virtual power plant synchronously. This setting has the advantage of facilitating the virtual power plant to adjust the aggregation planning.

[0048] For example, if the control mode of the electric boiler is determined to be the dispatch mode, the electric boiler is controlled based on the dispatch mode. If the control mode of the electric boiler is determined to be the manual mode, the electric boiler is controlled based on the manual mode. If the control mode of the electric boiler is determined to be the on-site mode, the electric boiler is controlled based on the on-site mode.

[0049] S104, starting a lockout mode, and controlling the electric boiler based on the lockout mode.

[0050] The lockout mode is to use the lockout control output as the current value of the electric boiler to control the electric boiler.

[0051] Specifically, if the working parameter does not meet the preset condition, the lock mode is started, and the lock control output is output to the current value of the electric boiler based on the lock mode, the electric boiler is controlled by the current value of the electric boiler, and the lock state is fed back to the virtual power plant at the same time, so as to facilitate the virtual power plant to adjust the aggregation planning again.

[0052] The technical scheme of the embodiment of the application comprises the following steps: obtaining a working parameter of an electric boiler; determining whether the working parameter meets a preset condition; if the working parameter meets the preset condition, determining a control mode of the electric boiler and controlling the electric boiler based on the control mode; and if the working parameter does not meet the preset condition, starting a lock mode and controlling the electric boiler based on the lock mode.

[0062] S204, determine that the control mode of the electric boiler is the dispatch mode, and acquire the preset load and the current control output of the electric boiler.

[0063] The preset load is a preset safe load of the electric boiler, and the current control output is a real-time load in the current working state of the electric boiler.

[0066] Specifically, after the preset load and the current control output of the electric boiler are acquired, the preset load and the current control output are calculated by difference to determine the first difference value of the preset load and the current control output.

[0067] For example, if the preset load acquired is 500 kW and the current control output of the electric boiler is 450 kW, the first difference value of the preset load and the current control output is determined to be 50 kW.

[0068] S206, according to the first difference value and the first control algorithm, determine the output load, and control the current control output of the electric boiler to be the output load.

[0074] S208, determine the control mode of the electric boiler as local mode, and obtain the current working temperature and the preset temperature of the electric boiler.

[0075] Wherein, the current working temperature is the working temperature in the current working process of the electric boiler; the preset temperature is the preset safe working temperature of the electric boiler, which can be 75 degrees Celsius, 80 degrees Celsius, 85 degrees Celsius, etc., which is not limited in the embodiment.

[0077] S209, determine the second difference value of the current working temperature and the preset temperature.

[0078] Specifically, after obtaining the current working temperature and the preset temperature of the electric boiler, the current working temperature and the preset temperature are calculated by difference, and the second difference value of the current working temperature and the preset temperature is determined.

[0079] For example, if the preset temperature is 85 degrees Celsius and the current working temperature of the electric boiler is 80 degrees Celsius, the second difference value of the preset temperature and the current working temperature is 5 degrees Celsius.

[0080] S210, according to the second difference value and the second control algorithm, determine the output temperature, and control the current working temperature of the electric boiler as the output temperature.

[0081] Wherein, the second control algorithm is u'(t) is the output temperature, K p is the proportional gain, K iK is integral gain d K is differential gain, e'(t) is the second difference value.

[0082] Specifically, after determining the second difference value, the second difference value is input into the second control algorithm In the second control algorithm, the output temperature u'(t) is calculated and determined, and the current working temperature of the electric boiler is controlled to be the output temperature.

[0083] S211, start the lockout mode, based on the lockout mode, control the current control output of the electric boiler to remain unchanged.
