Description

technical field

[0001] The invention relates to a control system, in particular to a control system for a magnetically controlled reactor. Background technique

[0002] With the rapid development of the power industry, the requirements for power supply capacity, voltage level, power supply quality and reliability are getting higher and higher. How to improve power quality, effectively reduce the pollution of reactive power to the power grid, and ensure the safe operation of the power grid has become an important issue in the electrical field. topic. The magnetron reactor is composed of the main winding and the control winding. The control winding provides the main winding with a certain size of controllable DC bias current through the thyristor. The DC magnetic flux generated by the DC bias current saturates the working iron core column, thereby making the magnetron Reactor capacity increases. Adjusting the size of the thyristor trigger control angle α can change the magne...
