[Abstract]:Based on the innovation team project of the Ministry of education, the innovation team project of the Liaoning provincial education department and the project of the Fushun coal mine motor manufacturing limited liability company, the 1140V/75kW flameproof integrated motor is taken as the research object, and the volume problem of the driving system caused by the narrow coal mine operation space and the integration of the variable frequency speed regulation system and the motor's high degree The speed estimation of the vector control of the degree sensor is easily affected by the influence of the measurement parameters and the system cost. The research on the hardware power design and speed estimation of the flameproof motor speed control system is carried out. The main contents of this paper include the following aspects:
In order to improve the system integration and reduce the volume and cost of the flameproof motor, based on the modeling of the power electronic system, the hardware power part of the variable frequency speed regulation system is designed. A method for calculating the capacitance parameters of the inverter bus is studied. The waveform of the rectifier output is analyzed in a period of time, and the voltage drop is considered. The ripple current, the mutual influence of the stability of the system, and the calculation of the bus capacitance value by Newton Raphson method. The simulation and calculation method of input current, line reactor voltage, bus capacitor voltage, busbar capacitance ripple current and output current are given.
In view of the restriction of the volume and temperature rise in the design of the flameproof motor, it is important for the correct design of the rectifier and the loss of the inverter for the correct design of the water-cooled radiator of the flameproof motor speed regulation system and the rational selection of IGBT. Based on this, an analytical method is proposed to calculate the IGBT loss of the inverter and the inverter. In the process of realization, the influence of gate drive resistance, DC bus voltage, temperature and junction temperature on IGBT loss is taken into consideration. The calculation method of conduction loss, switching loss, total loss, temperature difference and junction temperature of inverter IGBT and Diode under SVPWM modulation algorithm is given. Considering the characteristics of the mutual influence of IGBT loss and junction temperature, a custom heat path is taken into account. A cyclic iterative algorithm with the initial conditions of ambient temperature is proposed. Finally, the IGBT junction temperature, the temperature of the shell and the temperature of the radiator are given. The influence of the DC bus voltage, the gate drive resistance and the ambient temperature on the loss and temperature rise of the rectifier and inverter is quantitatively analyzed. On this basis, a water cooled radiator is designed and the flameproof is designed. The loss calculation of the main heating parts of the integrated motor is carried out, and the heat flow analysis is carried out by using the temperature simulation software. The simulation and experiment are compared.
The on-line adjustment of the MATLAB and Simplorer/Ansoft co simulation platform is carried out on the parameters of the current and speed regulator of the speed regulation system. The parameters of the correct PI regulator are optimized by the program, and the time for the tuning of the PI parameters in the system experiment is saved.
Based on DSP2812, the design of speed sensorless vector control program for flameproof motor speed control system is designed. In view of the large voltage fluctuation of the coal mine power system, the error of speed estimation caused by the strenuous fluctuation of the measured parameters in the process of speed estimation is increased, and the induction power based on fuzzy adaptive Calman filter is studied. By monitoring the ratio of the theoretical residual and the actual residual, by monitoring the ratio of the theoretical residual and the actual residuals, the measurement noise covariance matrix is recursively modified to make it gradually approximate to the real noise level, thus making the optimal estimation of the filter, improving the ability of the speed estimation strategy to resist the fluctuation of the measurement parameters and improving the accuracy of the estimation.
The structure design of the flameproof motor is made and one of the 1140V/75kW flameproof motor is made. The experimental platform is set up. The experimental research is carried out under the condition of load and load. It mainly includes the experiment of the switching characteristic under the condition of empty load, the different speed, the temperature rise experiment under the load torque, the PI parameter adjustment experiment, the sudden rising of the speed. The speed estimation experiments such as reduction, current disturbance and so on, verify the correctness and feasibility of the design of the flameproof integrated motor.
