Technical Electrodynamics| Summary: | The process of forming the transient voltage value on switching capacitors in the circuit of a conditionally twelve-phase controlled compensation converter (CTCCC), powered by a 6 kV electrical network in the mode of sequential direct start from it of four asynchronous machines (AM) with a capacity of 8 MW each, is considered. Possible means of limiting the overvoltage on switching capacitors are indicated, the most effective set of values of the parameters of their elements for implementing this action is found out. The most effective algorithm for controlling of the CTCCC thyristors is determined to reduce the value of the capacitance, which forces increasing in the compensation current. The starting transient modes that arise in the network as a result of starting such powerful AMs are research. References 10, figures 6.
