Study to TSC Reactive Power Compensation Equipment with Pre-charge Dynamic Non-transition Process

To solve shutting flow-current and operating over-voltage why are aroused by switch on/off capacitor frequently in safety,running,and energy quality researching field of power system,It is necessary to analyse the circuit model of capacitor switch-on/off by thyristor.Two necessary conditions of non-transition process switch on/off capacitor are needed,and in order to meet with these conditions,some problems about the structure of the main circuit should be solved;Secondly,the work principle of the TSC main circuit of pre-charge non-transition process is introduced in detail.Based on the work waveform,some items are expounded,which should be paid attention to when pre-charge dynamic non-transition process TSC trigger circuit is designed;Finally,the principle block drawing and the way to realize the TSC trigger circuit of pre-charge dynamic non-transition process are given.
