Adaptive control of a TCR for hybrid compensators using the energy distribution optimization approach

An energy related approach for the interpretation and subsequent compensation of electrical power networks is introduced. It is proposed that optimum supply utilization is brought about by the correct time distribution of the energy drawn from the source and supplied to a load. Hybrid compensators are proposed in order to perform cost-effective energy redistribution between the source, the load, and the compensators. A time-domain-based digital adaptive control technique for TCRs (thyristor controlled reactors) in such a compensation system is described. An optimum reactive current is calculated in the time domain, and a linear extrapolation predictor is further implemented in real time to estimate future values of the firing angles for the thyristors. This feature is implemented in order to improve the dynamic response of the system for changing load conditions.<
