LIMITATIONS OF CURRENT OF THE THREE-PHASE ACTIVE POWER FILTER IN THE CONDITIONS OF OVERLOAD AND SHORT CIRCUIT

Purpose. The purpose of the work is to develop a method of limiting the maximum allowable level of current of a three-phase active power filter in conditions of overload or short circuit and a system for the implementation of the method. Methodology. For research purposes, the provisions of the pq-t...

In the case of temporary overloads of current and short circuits at the network node to which a active power filter is connected, the current's limiting is performed by scaling the current to the level allowed by normal operation of the semiconductor elements of the device, which allows the basic operating algorithm to be implemented in the specified modes.
