With the advantage of high dielectric strength and low cost, capacitive voltage transformers (CVTs) have been applied to measure the voltage in power grid widely. Recently, CVTs own the problem of big error, insulation performance degradation and high failure rate due to the complicated environment. Secondary load is an important factor to impact CVT's accuracy by analysis. Consequently, we established...
Electromagnetic gun loading control system is based on the core chip of STM32F103VET6, and the measurement system based on LABVIEW. Displacement sensor and pressure sensor of signals are collected and transmitted via two USB to PC, it can be observed in real time online, at the same time, people can control the movement of the push rod status by PC to send commands. STM32 chip has low power consumption...
Solar power is a kind of clean and renewable energy, which can be utilized in the industrial micro-grid as an effective approach to decrease energy costs and reduce the emission of greenhouse. However, the uncertainty of solar power together with the limit of thermal power units' adjustment ability will bring a great challenge to keeping balance of power demand and supply. In this paper, the storage...
Modes in cylindrical waveguides with periodic subwavelength metal grating loaded on the inner surface are analyzed by both theory and simulation. Coupling between spoof surface plasmon mode and traditional waveguide mode provides a robust way to build TM02 single mode operation. Furthermore, a new approach to realize the well-integrated and reciprocal mode conversion between TM01 mode and TM02 mode...
With the development of wind power, how to use wind power fully has become an important research. In this paper, wind power accommodation robust model with security constraints considering demand response is built to accommodate wind power as much as possible. The robust model is a two-level optimal model: the upper level is to minimize the curtailed wind power and the lower level is to re-schedule...
It is important for both energy intensive enterprises (EIEs) and the utilities to analyze the electrical load tracking capacity of EIEs, so as to utilize resources in EIEs, and promote the participation of EIEs in Demand Response (DR) programs. An electrical load tracking problem integrating power generations self-scheduling (PGSS) and flexible load adjustment (FLA) is introduced. The relationships...
In this paper, the design of the conventional electron beam spreading system of the gyrotron collector consisted of the magnetic shade and two pairs of coils is presented. The simulation and experiment of the electron beam distribution on the collector wall of the gyrotron applied to the electron spreading system is completed.
