[0002] In recent years, due to the increase in industrial electricity consumption and the progress of urban and rural electrification, the electric power industry has developed rapidly, but at the same time it has also brought many problems, which has led to an increase in the demand for power reactors; the main performance In the following aspects: 1) The increase of the voltage level of the power system leads to the increase of the capacitive reactive power of the system, which increases the line voltage at no-load and light load, and requires shunt reactors to compensate to improve the line voltage distribution; 2) The power system uses From the perspective of improving economic benefits and reducing line loss, a large number of reactive power compensation devices are used, which requires a large number of series reactors; 3) The use of a large number of nonlinear loads leads to more and more serious harmonic pollution in the system. In order to improve the power Quality needs, a large number of passive power filters are put into use, and corresponding filter reactors are required

The electrical parameters of the reactor include the reactance, equivalent DC resistance, rated capacity and rated current of the reactor; among these parameters, the reactor's reactance calculation is the most influential to the design and manufacture of the reactor, that is, the reactor's Calculation of self-inductance and mutual inductance; because a small error in the calculation of inductance will cause a large change in the current distribution between layers, it is even easy to cause a large-amplitude circulation that only flows between individual layers This will not only increase the loss of the reactor, but also directly burn the reactor; therefore, when calculating the inductance, the accuracy requirements are extremely strict; in addition, the air-core power reactor is a multi-layer structure, when designing and calculating It is necessary to repeatedly calculate the self-inductance and inter-layer mutual inductance of each layer, and the calculation workload is very large; therefore, in the calculation of the inductance of the air-core power reactor design, the main problem is to seek high calculation accuracy and fast calculation speed. Fast calculation method, where the calculation accuracy is the first
