Simulation Analysis of a New Staggered Magnetic Valve Reactor Based on Two-Phase Composite Material

Magnetic The use of traditional magnetically controlled reactors can effectively improve the power quality of the power grid. However, it increases the complexity of the modern power grid structure to a considerable extent, and this complexity contains unreliability. Many power grid faults are caused by the failure of these devices. On the other hand, the traditional magnetically controlled reactor uses the control current to change the magnetic state of the reactor, which will produce a large number of harmonics and noise, seriously affecting the static and dynamic characteristics of the reactor and the stable and energy-saving operation of the entire power grid. At the same time, the smart grid has become the development direction of the future power grid. One of its main characteristics is that the equipment in the network can interact and adapt to the power grid. In this process, the simplification and rationalization of the power grid topology, the integration and intelligence of various device functions are the problems that the smart grid needs to solve. Because of the importance of the reactor in the intelligent power grid system, it is of great significance to develop a new type of magnetically controlled reactor and its control method. In this paper, a new type of electromagnetic valve reactor structure based on composite magnetic materials is proposed. The structure is improved in the traditional magnetic valve structure, and the manufacturing process is simplified based on the same performance as the traditional magnetic valve reactor. Combined with the low reluctance magnetic circuit design and magnetic coupling decoupling technology, the adjustment range and linearity of the reactance value are significantly improved. Using finite element simulation software, the magnetic flux distribution and reactance characteristics under different remanence conditions are systematically analyzed. The results show that the new magnetically controlled reactor structure exhibits excellent performance in magnetic flux conduction and energy utilization. The stability of the new structure under different operating conditions and the continuity of inductance value adjustment are verified by simulation. In addition, the finite element simulation further verifies the feasibility and effectiveness of the design. The new structure magnetic valve reactor based on composite materials meets the application requirements in terms of volt-ampere characteristics and control characteristics. This study provides theoretical and practical support for the performance optimization and technological innovation of magnetic valve reactors based on composite materials.
