Complex power control system for the installation of transverse capacitive compensation in the system with distributed load

Abstract

The operation of transverse capacitive compensation installations (CI) when they are switched on away from the power source (for example, at partitioning posts in the traction network or in general-purpose networks, for example, at branch points from main networks) under distributed load has a number of features. These features are considered on the example of an electrified railway section. In particular, the problem of controlling the power of the CI at medium and maximum loads is analyzed. Power control schemes of the CI have been known for a long time, usually regulation is performed to minimize power losses in the supply network, to reduce the maximum reactive power of the consumer, to stabilize the voltage mode in the power system node, etc. For electrified sections, regulation is typical to reduce power losses in the traction network or to stabilize the voltage at the AC traction network partitioning post. However, with the growth of heavy traffic on the railways, the requirements for increasing the capacity of railway sections while reducing electricity losses in the traction network have increased, that is, there are requirements for an integrated control system for CI. The complexity of solving this problem is determined by the fact that the CI is located at the partitioning post. The article offers an algorithm for solving this problem using the harmonics of the electric rolling stock current.
