Abstract

The invention provides dynamic simulation device and method thereof of a super and extra high voltage controllable magnetic control shunt reactor, wherein the dynamic simulation device is capable of accurately simulating magnetic control shunt reactors with different capacities in 500kV, 750kV and 1,000kV power transmission systems. A simulation body consists of three single-phase magnetic control reactors; each single-phase magnetic control reactor is in a three-column structure; two beside core columns are working iron cores; a main alternating current winding and a direct current control coil are wound on each working iron core; and main alternating current windings on the two iron core columns are connected in parallel and connected to a power grid. Control windings are separated fromthe main windings so as to ensure the safety and the reliability of the device during work. The main windings are provided with twelve turn-to-turn short circuit taps which can respectively simulate 1-25 percent of turn-to-turn short circuit faults from the high-voltage side and the neutral point side; and the control windings are provided with seven turn-to-turn short circuit taps which can simulate 1-25 percent of turn-to-turn short circuit faults from the neutral point side. The body of the device is provided with a current transformer and a voltage transformer on a primary side, which areused for meeting the requirement for protecting a reactor body in a dynamic simulation test.

Description

technical field [0001] The invention relates to a dynamic simulation device and method for an ultra-high voltage and ultra-high voltage magnetic control type controllable shunt reactor and belongs to the field of dynamic simulation systems of power systems of various voltage levels. Background technique [0002] The controllable shunt reactor can automatically adjust its own capacity with the change of transmission power of the line, and can reduce the overvoltage level of the line operation and improve the operating efficiency of the power grid; respond quickly to the dynamic stability caused by the system disturbance, suppress voltage fluctuations, and improve System stability, increase power transmission capacity, and suppress system power oscillation. The application of controllable shunt reactors in EHV and UHV transmission systems has become one of the development directions of power systems. In order to further improve the dynamic simulation ability of ultra-high vol...
