Abstract

The invention provides a control method for a TCS drop-compensation solid-state soft starting device. The control method comprises the steps that: S1, the TCS drop-compensation solid-state soft starting device is debugged; S2, input power grid parameters, motor parameters and equipment configuration parameters are calculated according to a TMS algorithm, and a step-down transformer tap voltage with an optimal starting effect is recommended; and S3, the step-down transformer tap voltage with the optimal starting effect is adopted, and one-time smooth starting of the TCS drop-compensation solid-state soft starting device is achieved. By adopting the adaptive TMS deep learning algorithm, the step-down transformer tap voltage with the optimal starting effect can be obtained under the condition that data such as system parameters are complete, and one-time starting success is guaranteed.

Description

technical field [0001] The invention relates to the technical field of solid state soft starter with reduced compensation, in particular to a control method and system for a TCS reduced compensation solid state soft starter. Background technique [0002] The power factor of the motor is very low during the starting process, so that the motor will consume a large amount of reactive power in the grid during the starting process. Therefore, when the motor is started directly, the starting current is usually 6 to 7 times the rated current of the motor. The consumption of a large amount of reactive power will cause The drop of the grid voltage, if the grid voltage drop is too large during the starting process, will seriously affect the normal use of other equipment in the grid. The TCS step-down compensation solid-state soft starter is used to realize the soft start of the motor, mainly including a voltage reducer, a reactive power generator, a voltage reduction control cabinet a...
