Some embodiments of the invention are described in detail below with reference to the accompanying drawings. It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
Referring to fig. 1, the present embodiment provides a mobile power supply system 100, which can effectively improve the stability of the system. The mobile power supply system 100 comprises a display and control console 10 and at least two mobile power stations 20, wherein each mobile power station 20 comprises a controller and a communicator, each communicator is in communication connection with each controller and the display and control console 10, and the communicators are in communication connection with each other.
The controller is used for controlling the working state of the corresponding mobile power station 20, or the display and control console 10 is used for controlling the working state of the mobile power station 20.

And the priority of the control is higher than that of the remote control, and the seamless switching of the control mode can be realized through a control mode change-over switch arranged on the controller.

It should be noted that, taking the above first power station and second power station as an example, the first controller may directly send a control instruction to the second controller through the first communicator, may also send a control instruction to the second controller through the second communicator, may also send a control instruction to the second controller through the first communicator and the second communicator, and similarly, may also receive parameter information of other controllers through the above multiple modes, so that the multiple sending and receiving modes may better ensure the stability of the system.
Moreover, because the controllers can be mutually controlled, and any one controller can obtain the parameter information of other mobile power stations, even if one controller breaks down, the control and the operation of other mobile power stations are not influenced, and the stability of the system is further improved.
In a possible embodiment, each mobile power station 20 further includes a data collector, and the data collector is connected to the communicator and the controller, respectively, and is configured to collect parameter information of the mobile power station 20 and transmit the parameter information to the communicator and/or the controller.

Two measurement modes are described below:
mean value measurement mode
The measurement mode comprises the following steps: alternating current buck sampling, AC-DC rectification, low pass filtering, and PID control PWM regulation. This measuring method is under linear load, the voltage waveform is sinusoidal good, the harmonic content is very little, and under nonlinear load, voltage waveform distortion, the harmonic content is very big, although through filtering higher harmonic component behind low pass filter, but also can cause measuring signal's energy loss simultaneously, at this moment, AVR voltage regulator can misjudge for external voltage low thereby increase excitation, cause generator output voltage to rise, parallelly connected power distribution deviation is big, and simultaneously, the nonlinear load of pulsed causes generator voltage harmonic content strong and weak hour, high and low hour during measuring signal, cause voltage fluctuation, influence parallelly connected stability.
Effective value measuring method
Referring to fig. 4, the measurement method includes: alternating current buck sampling, an AC multiplier, low pass filtering, and PID control PWM regulation. In the measuring mode, under any load, the measuring signal passes through an internal AC multiplier and a low-pass filter, and no higher harmonic component is lost. Therefore, under the pulse nonlinear load, the AVR voltage regulator has high control precision and good stability, and the parallel connection characteristic of the system is greatly improved.
