The paper presents one kind of voltage compensation means that based on phase-shift control,which could make the load voltage constant when the voltage of the grid fluctuated and have a good harmonic filtering capabilities.

Based on voltage compensation principle, a superconducting magnetic energy storage-current limiting (SMES-CL) integrated system is proposed by integrating series SMES (SSMES) and fault current limiting inductor.

The system analysis modei of series voltage controller is built, and the effects of transformer s internai resistance and leakage reactance on its voltage compensation characteristic, when it adopts open-loop and closed-loop control strategies, are investigated, respectively.

By theory computing, the principle of high-field asymmetric waveform ion mobility spectrometer was analysed,and the relationship between compensation voltage and asymmetric waveform RF voltage was deduced.

While the tiltmeter can not record normally because the pendulum deviates from the zero point, the auto zero point adjustment circuit can produce a precise compensation voltage to adjust the pendulum to the zero position.

According to the practical requirement of armored car,taking the method of voltage compensating,a high performance military computer power supply is designed by using DC/DC modules.

The color measurement system takes silicon photocell as its photo detectors,the temperature characteristic of silicon photocell would produce influences to the measuring stability of system,and proper voltage compensating is needed to make the performance indicators more excellently.

A novel shunt reactor interturn protection scheme is proposed based on zero-sequence compensated voltage magnitude comparison.

Using the vector plane analysis and impedance plane analysis,this paper presents a fault-component based distance relay construction method which uses the pre-fault compensated voltage as datum component.
