Since Hulunbuir-LiaoNing HVDC transmission project was put into operation, low amplitude subsynchronous oscillation had occurred frequently and exceedingly in Hulunbuir power plant, such problem was of serious concern to power plant and power system operators. This paper calculated the complex torque coefficients of the units in Hulunbuir power plant using complex torque coefficient method based on...
In this paper, a continuous wave (CW) low-voltage fundamental harmonic W-band gyrotron has been designed and simulated with the help of a particle-in-cell (PIC) software CHIPIC. The output power of 33.4 kW with an electron efficiency 37.1% in the PIC simulation is obtained by the designed conventional gyrotron employing a 30-kV, 3-A electron beam which is produced by a triode magnetron injection gun...
The more efficient use of by-product gas has always been a hot issue in the iron and steel making process. The gas generation during production process is stochastic and hard to predict accurately. Specifically, how to regulate the supply of by-product gas from gas holder to power plant in the scheduling period to maximize the total profit of gas reutilization is presented in this paper. In response...
A W-band four-cavity gyroklystron amplifier has been studied using the particle-in-cell (PIC) code. The amplifier operates in the fundamental harmonic TE01 circular electric mode. The simulation predicts 143kw output power at W-band with 33.8% efficiency, 37dB gain and 1GHz bandwidth.
In this paper, a high-power microwave amplifier system is discussed with main emphasis on the method of control and detection, which can protect the core component of the amplifier system - traveling wave tubes (TWT) effectively, detect the real-time input and output power of the amplifier system and caculate the data which detected from the amplifier. In this system a human machine interface (HMI)...
