HIFU Power Monitoring Using Combined Instantaneous Current and Voltage Measurement

Measurement of Harmonic Voltage, Current, and Power at Industrial Frequency

Measurement based Voltage Stability Monitoring of Power system

Many papers discuss the voltage stability assessment of power system using power flow analysis methods. In this paper, a method for online monitoring of a power system based on measurements is proposed, which is aimed at detection of the voltage instability. Thereby an indicator is derived from the fundamental Kirchoff-Laws. Since in the transient process, at any time point, the electric power ...

Power voltage current convertor using quasi complementary MOSFET current mirrors.

A voltage current convertor is described having a quasi complementary class AB architecture that is particularly suited to implementation using discrete power MOSFETs. High-voltage mirror designs are presented, enabling the construction of sources with kilovolt compliance range, tens of watts of output power and greater than 100 kHz bandwidth. GΩ output impedance and distortion below 1% can be ...

Reactive Power Pricing in an Open Access Environment Considering Combined Optimum Voltage Profile and Voltage Stability

In a de-regulated open access environment, reactive power is one of the ancillary services which must be provided by an Independent System Operator (ISO). In this paper, a new algorithm is proposed in which reactive power resources are initially so tuned that optimum security in terms of voltage profile and voltage stability are achieved while at the same time, the system losses are minimized. ...
