As the event sequence diagram (ESD) methodology is used for modeling the complex system, the event simply describes system configuration and status in order to control the size of the model, so the model can't directly reflect the design and operation limitation. According to the hierarchy feature for the structure of nuclear power plant, a layered modeling of ESD is presented for marine nuclear power...
Neutral inductance of shunt reactor is an important component of shunt reactors. In this paper, the operating characteristics to suppressing frequency resonance overvoltage and reducing secondary arc current is elaborated. And the value of the neutral inductance should be determined according to the degree of compensation of the shunt reactor. So some research on the controllability of neutral inductance...
A 2.9 GHz quadrature VCO designed in a 0.18 um CMOS process achieves a very wide tuning range of 77% when the supply voltage equals 1.8 V. The phase noise is -120 dB/Hz at 1MHz offset for the oscillation frequency of 2 GHz, and -104 dB/Hz at 1MHz offset for the oscillation frequency of 4 GHz. The coupled oscillator architecture is adopted to widen tuning range and to minimum phase noise. Accurate...
Through analyzing the typical systempsilas characteristic and Ultra-High Voltage(UHV) ac transmission linepsilas characteristic, the strategy by controllable shunt reactor is presented to improve transmission quality in electric networks in this paper. By using MATLAB PSB, simulation model of UHV ac transmission line from Jindongnan to Jingmen was built to study control effects on frequency over voltage,...
