Accelerator System

There is presented a system of registering electric parameters of high-current pulsed electron accelerator “Gamma-1” its output electric power being 1.5 TW. The accelerator system of registration makes it possible to register in a single time scale the voltage pulses with the amplitude up to 3 MV, current pulses with the amplitude up to 1 MA and duration from several nanoseconds to a microsecond. Into the system of registration there are included two-step resistive voltage dividers, capacitive voltage divider, Rogowski coils, sectionalized Rogowski coils, B-dots, shunts, transmission line, attenuators, oscilloscopes, program system. The program system is aimed at reading, transmitting and processing information from oscilloscopes on the archival computer and provides interaction with database of current and voltage sensors, cables and filters. For each registration session the system also forms a map of experiment where system configuration and experiment parameters are presented.

Bidirectional Power Flow

With the recent push for renewable energy several former consumers units now have energy generation capabilities. While this approach is beneficial in general, it also poses new challenges for cooperation and grid stability. The new smartgrid now needs bidirectional power flow, data communication, and intelligent controls in order to ensure reliable operation. Voltage sensing plays a key role, capacitive voltage transformers have been demonstrated useful for high- voltage (100kV+), but have not yet been discussed for low (220V) and medium (13kV) voltage. This paper proposes a simplified capacitive voltage divider circuit for low-voltage measurement. Mathematical modelling is used for steady-state operation, circuit design, and sensitivity to analysis. Monte-Carlo simulations are employed to verify the effect of component tolerances, indicating under 0.7dB gain, and 0.03° error at fundamental frequency. Experimental validation is performed at low-voltage levels (127V), indicating 0.5 dB magnitude and 0.3° phase deviation at fundamental frequency. Performance is also validated from 60Hz to the 50th harmonic, showing 20° phase deviation at the higher order harmonics (16th and up). From the obtained results it is expected that the sensor is sufficient for voltage quality measurements, but should be software-corrected if power measurement is required at the high-order harmonics.

Capacitive Voltage Divider

A ims . A kind of two levels self-integrating capacitive voltage divider is designed to online measure high voltage nanosecond pulse. Methods. The circuit principle of capacitive divider is analyzed, and the theoretical voltage ratio is calculated. The calibration is carried out by using a low voltage pulse source. The divider with a primary voltage divide ratio 601 has been tested to frequency response exceed 1GHz. The second voltage divide ratio can be set flexibly using different ratio attenuators according to the different voltage level of the source. Result. Finally, this divider is used in measuring 600kV high voltage pulse source, and the experimental results show that the present coaxial capacitive divider is reliable and satisfactory for the measuring requirement in time domain and frequency domain.
