Microprocessing control of reactive power compensator
Euromicro Newsletter, 1979Abstract This paper presents a method of reactive power compensation, using a microprocessor controlled thyrister switching of capacitor banks. The microprocessor provides the necessary timing of the switching process to avoid harmful supply transients and permits levels of compensation in each cycle.

Reactive Power Control Strategies for DFIG-Based Plants
IEEE Transactions on Energy Conversion, 2007This paper explores and compares the performance of alternative voltage control strategies applied to doubly fed induction generator (DFIG). Different combinations of reactive power control of rotor- and grid-side converters are investigated for voltage-control purposes. Simulations are performed using detailed models built in DIgSILENT PowerFactory in

Reactive Power Balance and Voltage Control
1997Economic considerations have generally resulted in short-term generation unit commitment practices and trading procedures placing considerable emphasis on scheduling active power to meet system demands. Voltage control is usually managed as a second step in the operation of the power system.

Power flow control with controllable reactive series elements
IEE Proceedings - Generation, Transmission and Distribution, 1998The basic features of controllable reactive series elements (CRSE) (i.e. controllable series compensation (CSC) and a static synchronous series compensator (SSSC)) for system power flow control are presented. Mathematical models of CRSE, including a simplified transmission system model, have been developed.

Reactive Power Control of Wind Plants
2014The intention of this chapter is to describe a reactive power control structure for wind turbines and wind plants that provides the necessary capability to ensure a stable system voltage in the medium and high voltage grid even if no synchronous generation is present any more.

Reactive power generation and control by thyristor circuits
1976 IEEE Power Electronics Specialists Conference, 1976Generally, static var generators function as variable reactances (capacitive or inductive impedances) or controllable ac current and voltage sources. Possible methods of var generation and control by static thyristor circuits are reviewed, and new approaches are described in which power frequency changers (cycloconverters) are employed.

Grid Voltage and Reactive Power Control
2015A widespread inadequate control of grid voltage and reactive power has become more critical in recent years due to the general trend by system operators and electrical utilities to operate transmission networks as close as possible to their maximum capacity.
