Modes of Interphase Power Controller Operation

Abstract

The IPC (Interphase Power Controller) technology is a developing direction in the domain of power systems interconnections. The practical application of these devices will improve the efficiency of power systems operation and prevent the spread of undesirable phenomena in electric networks. This may result in new regimes effects that require special consideration and analysis. The paper discusses some features of IPC operation at the installation of it on the input end of transmission line. The purpose was to study the characteristics of the transmission line, when on the transmitting end was mounted uncontrolled IPC with centered characteristics. Additional ways of using the phase shifting transformers (PST) to adjust the power characteristics of IPC are considered as well. In this case the PST acts as a reactive power compensator. Favorable conditions IPC operation can be obtained by applying an additional phase-shifting element mounted IPC for power at the receiving end. It is concluded that the installation phase-shifting device (beginning or end of the line) does not matter and it can be determined based on specific conditions. Results testify the possibility of full harmonization of IPC with the line in all practical cases.
