It is well-known that traditional LCC HVDC system is not capable of control its reactive strength and terminal AC voltages. This paper investigates the reactive electricity and AC voltages manage at the inverter aspect of the LCC HVDC system with controllable capacitors. The system’s capability of operating below poor extinction angle is utilized to reap a wide range of reactive energy control and, mainly, the capacity of exporting reactive electricity. The effectiveness of the reactive strength/voltage control functionality for the proposed device is demonstrated via simulation outcomes the use of actual Time digital Simulator (RTDS). To verify the effectiveness of the reactive electricity and voltage control, CCC HVDC and LCC HVDC with SVC are also set up in RTDS. The proposed idea makes an integration of Fuzzy good judgment which assists in accurate control of capacitors and makes the device green by means of lowering the consumption of Reactive energy. All of the outcomes are acquired from the MATLAB simulations and numerous graphs are plotted.

<span>In this paper, a new approach is proposed for keeping the RMS voltage output constant, the system is supplying by a self-excited induction generator (SEIG) driven by a controlled DC motor with variable speed and load. The scheme used in this paper is based on a classical Proportional-Integral regulator wich controls a SPWM switching. A MATLAB Simulink model of the system is developed to maintain the AC voltage at the desired value. Then a comparison is examined between simulation and experimental results using dSPACE board. The results are provided to verify the effectiveness of this approach and it gives very high performance.</span>

Electron Energy Loss

A double focusing magnetic spectrometer has been constructed for use with a field emission electron gun scanning microscope in order to study the electron energy loss mechanism in thin specimens. It is of the uniform field sector type with curved pole pieces. The shape of the pole pieces is determined by requiring that all particles be focused to a point at the image slit (point 1). The resultant shape gives perfect focusing in the median plane (Fig. 1) and first order focusing in the vertical plane (Fig. 2).
