Abstract: In order to improve the speed regulation performance of automatic frequency conversion of electrical equipment, a speed regulation method of automatic frequency conversion of electrical equipment based on double-fed speed regulation device is proposed. According to the allocation of the sliding window, divide the state data of electrical equipment, use the Gaussian kernel function to monitor the operating state of equipment, calculate the back EMF of the stator winding according to the actual speed and slip of the double-fed speed regulating device, and realize the speed regulation of frequency conversion through the synchronous control of the back EMF and frequency. The experimental results show that the method in this paper can control the electrical equipment to run at the expected speed under the conditions of constant load and disturbance after regulating the automatic frequency conversion speed of electrical equipment, and the response time is short, improve the working efficiency.
Keywords: double-fed speed regulation device; speed regulation; frequency conversion speed regulation; automation; electrical equipment
