Abstract

The invention relates to a driving control device based on a dynamic voltage restorer. The device comprises: a silicon controlled rectifier module connected between a power grid and a load and used for controlling the on-off of the power grid and the load; and a DSP controller electrically connected with the silicon controlled rectifier module and used for receiving a control instruction, sendinga control signal to the silicon controlled rectifier module according to the control instruction and driving the silicon controlled rectifier module to work in a delayed manner. According to the driving control device based on the dynamic voltage restorer, the delayer is added to carry out delay driving on the circuit, so that the problem of potential safety hazards caused by uncontrollability ofsilicon controlled rectifiers in the prior art is eliminated.

Description

Technical field [0001] The invention relates to the field of automatic control, in particular to a time-delay driving device based on a dynamic voltage restorer. Background technique [0002] Dynamic voltage restorer is an industrial equipment that solves the problem of voltage sag in power quality. Among them, the thyristor module, as the core device between the power grid and the load, is mainly used as a switching device for disconnection and conduction between the load and the power grid. When the power grid dips, the thyristor needs to be disconnected. At this time, the dynamic voltage restorer starts to work to ensure the normal operation of the load; when the power grid is restored, the thyristor is closed again, and the dynamic voltage restorer is in a standby state. At the beginning of the dynamic voltage restorer is powered on, the entire system has a self-check process, during this period we need to ensure that the thyristor is turned off. [0003] The traditional thyr...
