Control structures and strategies have a critical influence on a power electronic converter’s behavior during disturbances. Most of the previous works in the field of pulsewidth modulation voltage-source converter (VSC) operation under unbalanced condition ...
The calculation of AC loss due to the control currents in ITER is a cumbersome task. The reason is that control transients require small field changes (0.1 T or less) at moderate frequency (up to 10 Hz), where effects of partial penetration of the filament ...
Steady operating conditions of an extra-high-voltage power line equipped with controlled shunting reactors are considered. The required control of the reactors is shown that enables the permissible levels of voltage at intermediate points of the power line ...
The present paper describes the modeling of Unified Power Flow Controllers (UPFC) for studying the steady-state and transient behavior of electrical networks equipped with FACTS devices. Detailed time-domain simulations are carried out on four model power ...
An in situ methodology is proposed to characterize the impedance mismatch at each power line communication transmission port in medium voltage network. Based on path loss and impedance measurements, a complete characterization of a non energized medium vol ...
The growing demand for the solid-state meters for power and energy measurement leads to the fully integrated Hall-sensor-based microsystem solutions. In this paper, a silicon-on-insulator (SOI) Hall-sensor-based. microsystem for energy measurements with dy ...
In order to improve the transfer capability of the 220-500 kV AC transmission system that forms the power network backbone in the Russian Far East interconnected power system, two new generation system protection schemes complexes were put into operation a ...
This work describes a development of a control system and control strategies capable of governing multiple flexible AC transmission system (FACTS) devices. The main purposes of the presented coordinated control system are to remove overloads and to achieve ...
Hybrid asymmetric multi-level inverters promise significant improvements for medium-voltage industrial drives. Floating sub inverters without feeding can only supply reactive power. An on-line non-linear model-predictive controller stabilizes their interme ...
Nowadays, multilevel VSIs (Voltage Source Inverter) begin to be widely used in middle and high power installations such as variable speed drives, FACTS (Flexible AC Transmission System) and windformers for example. In these systems, 2 VSIs are put back to ...
