Description

Intelligent adjusting device and method for water pump motor and cloud platform control method
Technical Field
The invention relates to the field of water pump adjusting devices, in particular to an intelligent adjusting device and an adjusting method for a water pump motor and a cloud platform control method.
Background
The agricultural power grid system is generally shown in fig. 1 and is divided into: 1. the system comprises an upper main transformer 2, a power supply line 3, a field transformer 4 and a final user side water pump. The vector relationship of the power supply system is shown in fig. 2, where U0 is the main transformer outlet voltage, Ue is the field transformer inlet voltage, Uxr is the resistive voltage component of the line, and Uxl is the inductive voltage component of the line (since the power supply is longer, there is a certain line impedance in the line, and the line impedance is larger the longer the line is, and the line impedance can be divided into the resistive component of the impedance and the inductive component of the impedance). It can be seen from fig. 2 that the Ue voltage is much lower than U0 due to the large line voltage drop, which results in the user using too low voltage.
There are generally three solutions to this problem in the prior art:
1. the voltage regulating device (such as a tap of a variable transformer) is used to boost the voltage at the user end, and the vector diagram is shown in fig. 3, where Ut is the boosted voltage. Although the problem of low terminal voltage of a user is solved by the solution, the solution does not solve the problem fundamentally, and the following problems still exist: (1) the problem of energy consumption: the method is to absorb part of the energy in the power grid so as to increase the terminal voltage of a user, thus increasing the current in a line and increasing the line loss. (2) Problem of grid fluctuation: in order to prevent the power grid from fluctuating too much, a dynamic step regulation mode is generally adopted to boost the voltage, but the dynamic step regulation mode is accompanied by some problems such as equipment reliability and the like.
2. The voltage is boosted by a parallel compensation method, and the method also has the following problems: problem of voltage rise range: the method can only improve the power factor of the user terminal as much as possible so as to reduce the current in the loop and reduce the line voltage drop, but the reduction is very limited, so that the problem of low voltage of the user terminal cannot be fundamentally solved.
3. The voltage is boosted by a series compensation method, and although the method can fundamentally solve the problem of low voltage of a user terminal, the following problems also exist: (1) the equipment reliability problem is as follows: the method is generally to connect the capacitor directly in series into the power supply loop, so that the requirement for the capacitor itself and the components such as the insulating member and the like matched with the capacitor itself is very high, and if the components in the device have problems, the whole set of equipment is likely to be damaged, and the power supply network is likely to be broken down. (2) The problem of grid stability: because a certain amount of inductive reactance exists in a circuit and a load, the inductive reactance and a series capacitor are very likely to generate resonance when the power grid or the load fluctuates, the device has no regulating function, so the resonance cannot be avoided and attenuated through regulation, and the stability of the whole power grid is greatly threatened.

Namely, when the device of the embodiment is in an online state, the adjustment can be carried out according to a control instruction sent by the cloud platform, and when the device is in an offline state, the optimal operation state of the water pump motor in the current power distribution network line under which voltage and frequency can be achieved is judged according to the prestored control logic.
