Many analyses are required to locate a new reactive power source in a power system. The choice of a location is a very complex matter which requires various aspects to be considered. Selecting a location also entails the necessity to assess it from the point of view of the selected compensator’s structure as well as the system’s performance in various states with the new device on.
The paper presents the issues of assessing compensator location from the point of view of resonance phenomena. It indicates the factors which affect a circuit’s resonance conditions, including a change in network configuration and compensator’s structure.
