Control method for outputting maximum power through wave power generation and related device

Abstract

The present invention discloses a control method for outputting a maximum power through wave power generation. The method comprises the steps of: measuring a working speed of a generator by a sensor,performing Kalman filtering processing of a measured value, and obtaining a speed value after filtering; performing calculation processing of the speed value after filtering according to a maximum power acquisition algorithm, and obtaining a Q-axis desired current value; performing control signal obtaining processing of the Q-axis desired current value, and obtaining control signals; and performing control of a rectifier according to the control signals to allow the generator to work in the maximum power state. Feedback input of the maximum power control through adoption of the Kalman filtering is performed, namely, the actual measured speed is filtered to obtain a feedback input speed value being closer to reality, and therefore, the control strategy accuracy can be improved, the maximumpower can be more accurately captured and the efficiency of the whole wave power generation device can be improved. The present invention further discloses a control system for outputting the maximumpower through wave power generation, a control device for outputting the maximum power through wave power generation, and a computer readable storage medium which have the beneficial effects mentionedabove.

Description

technical field [0001] The present application relates to the technical field of power generation, and in particular to a control method, a control system, a control device and a computer-readable storage medium for maximum output power of wave power generation. Background technique [0002] The use of ocean energy is the direction of energy research in the world today. Especially in the situation that energy is related to national security, the earth's mineral energy is gradually depleted and the environmental situation is deteriorating, how to effectively use resource-rich and renewable marine resources is very important. Inertial wave power generation technology is the use of ocean waves. On the basis of energy generation research, use mature machinery manufacturing and power generation technology for effective combination. [0003] Wave power technology converts wave energy into electricity. The conversion of wave energy generally has three stages. The first stage is ...

Problems solved by technology

[0005] However, in the general control strategy, the speed data needs to be collected by the sensor. Due to the high energy density of the wave, the cycle frequency is not constant, and the ocean environment is harsh, it is easy to cause the sensor measurement error to seriously deviate from the true value of the data.

The control signal of the control strategy is seriously distorted, and the accuracy of the control strategy is seriously reduced, which makes the efficiency of the entire wave power generation system low.
