Special Issue Information

Dear Colleagues,

The frequency conversion drive technology of AC motors and converters is a common key technology in high-end manufacturing industries, such as intelligent manufacturing equipment, aerospace equipment, ship and ocean engineering equipment, and advanced rail transit equipment. Frequency conversion drive technology has been further applied in emerging fields, such as wind power generation systems and high-end energy equipment, playing an important role in promoting the development of green energy. However, variable frequency drive technology and its application in complex scenarios face a series of challenges, such as equipment upsizing, energy efficiency issues, system stability issues and control complications, which deeply affect industrial upgrading and energy transformation strategies.

In order to solve the above-mentioned problems and challenges, it is necessary to further study advanced control technologies—such as grid converter control, model predictive control and field weakening control—and explore more efficient power electronic converter and generator design technologies.

In summary, the frequency conversion drive technology of AC motors and converters has broad application prospects and great research value. Thus, this Special Issue aims to promote the progress and development of technology in this field and will cover the following areas:

  1. Fault crossing active support technology for wind power systems.
  2. Power electronic converter and system modelling, stability and control technology.
  3. Stability analysis and control technology of wind power grid connection.
  4. Grid connected converter control.
  5. AC motor speed/position sensorless control technology.
  6. New topology of AC motors.
  7. Wind power generation system based on doubly fed motors.
  8. Control of offshore wind power generation systems.
  9. Innovative theories and key technologies that intersect with the above fields.

Position sensorless control has been widely used in permanent magnet synchronous motor (PMSM) drives in low-cost applications or in the fault-tolerance control of position sensors. Conventional sensorless control methods often adopt a back electromagnetic force (EMF)-based position observer, which results in bandwidth reduction in signal processing and lower estimation accuracy. This paper introduces a numerical solution based on transmission line modeling (TLM) to obtain the back EMF. The TLM method is used for the numerical calculation of electromagnetics due to the clear algorithm structure, robust convergence and stability, and easy implementation in dynamic circuit analyses. This paper first analyzes the 2D TLM method techniques. Then, a new application of TLM theory in position sensorless control of PMSMs is put forward. The proposed TLM-based sensorless control scheme can estimate the back EMF without decreasing the bandwidth, thereby enhancing the dynamic performance of the sensorless control. All numerical results are implemented using the proposed approach, which validates the effectiveness of the proposed method. Full article

In order to solve the problem that the impedance of each line of the parallel system of the wind–solar–storage virtual synchronous machine (VSG) is inconsistent, resulting in the power circulation between the parallel VSG, a multi-parameter collaborative adaptive control strategy for the parallel virtual synchronizers of a wind–solar–storage microgrid based on a neural network was proposed. Firstly, the topology of the virtual synchronous machine parallel system of the wind–solar–storage microgrid was built, and the VSG was analyzed. Then, the neural network algorithm was used to realize the adaptive adjustment of each parameter of VSG, which improves the uneven power distribution and the influence of circulation. Next, the parameters of multiple parallel VSG control systems were configured. Finally, MATLAB2021a/Simulink was used to model the system, and the VSG capacity under different scale conditions was simulated and analyzed. The simulation results show that when the capacity ratio of VSG1 and VSG2 is 1:1, the active power output is 9000 W, and the reactive power output is 7500 Var, which realizes accurate distribution, and when the capacity ratio of VSG1 and VSG2 is 2:1, the output values of active power and reactive power are 12,000 W/6000 W and 10,000 Var/5000 Var, and the output is carried out according to the ratio of 2:1, which shows that the control strategy can effectively improve the power allocation accuracy, suppressing circulation.
