Zone Reactive Power Controller
2018 IEEE 4th International Forum on Research and Technology for Society and Industry (RTSI), 2018In this paper zone reactive power controller is presented. Power network is naturally divided into voltage areas which are semi-independent or, at least, have no significant impact on neighbouring areas. Natural voltage areas, zones, represent the impact range of control actions performed in a certain zone.

Control of reactive power and voltage in emergencies
Automatica, 1985A method is introduced which assures quite feasible computation of control actions to be taken to remedy voltage problems resulting in a section of a system because of a disturbance. The process is devised so as to conform to the natural structural features of the problem. A monitoring process is proposed.

Provision for reactive power market in the reactive power control groups
TENCON 2008 - 2008 IEEE Region 10 Conference, 2008Implementation of electricity market is facing many challenges in developing countries like India. The market for real power is gaining more interest of investors while the market for reactive power has less incentive due to its technical limitation. But reactive power is of importance for system security and improving the line transmission capacity ...

Reactive Power Control of Compound Reactive Power Compensation Device
2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018A low-cost composite reactive power compensation model is proposed. The model consists of a Thyristor Switched Capacitor (TSC), a Thyristor Controlled Reactor (TCR) and a Static Var Generator (SVG). Firstly the paper completes the preliminary compensation by the large-capacity TSC+TCR module, and then the small-capacity SVG is responsible for ...

OPTIMAL CONTROL OF VOLTAGE AND REACTIVE POWER OF POWER SYSTEM
IFAC Proceedings Volumes, 1987Abstract In this paper, from the view point of economy and security of a power system, a synthetic mathematical model is presented for minimizing system losses and improving voltage level. At the same time, it is taken into account that when the reactive power is insufficient or it is hard to operate the system normally, the system will be supplied ...

Active reactive-power controller
IEE Proceedings - Electric Power Applications, 1995A novel technique for building reactive power compensators using the switched-capacitor technique is presented. Normally when switched-capacitor are used for reactive power compensation they are operated at the supply frequency; in the proposed technique the capacitors are switched at higher frequencies, typically 800 Hz.

Reactivity and Power Shape Control
Nuclear Science and Engineering, 1977An optimization method, based on linear programming, has been developed that determines the enrichment distribution in a multizone reactor such that the desired power distribution is achieved at beginning-of-life conditions, as well as the poison distribution during reactor operation such that the reactor is kept critical and the desired power ...
