“…These main advantages of analog approach enable us to represent, in real time, the state of electric and/or electronic power systems. Thus, new solutions for diagnosis which facilitate the maintenance of the electrotechnical equipments can be considered [16][17][18][19][20]. In this area, few studies are available in the literature especially for the modeling of command circuits [1][2][3].…”

An analog behavioral model of high power gate turn-off thyristor (GTO) is developed in this paper. The fundamental methodology for the modeling of this power electronic circuit is based on the use of the realistic diode consideration of non-linear junctions. This modeling technique enables to perform different simulations taking into account the turn-on and turn-off transient behaviors in real-time. The equivalent circuits were simulated with analog software developed in our laboratory. It was shown that the tested simple and compact model allows the generation of accurate physical characteristics of power thyristors under dynamic conditions. The model understudy was validated with analog simulations based on operational amplifier devices.

Renewable energy technology has great potential for generating power at a profitable level that concurrently befriends the environment. However, some technologies come with negative factors that limit its market penetration. For wind power, the quality of the generated power limits its extensive use. The main concern for the quality of wind power installations is the fluctuation of voltage levels, which can be attributed to transient states where of the wind turbine generators are first connected to the grid, steady-state levels attributed to the inherent nature of injecting power to the grid, momentary disruptions due to wind gusts and general wind speed variations. This paper adopts the One Cycle Control (OCC) method in a series connection topology, which here acts as a Unified Voltage Quality Conditioner (UVQC), to deal with most of the problems identified above. The new OCC-UVQC has many advantages including no reference calculation resulting in great simplicity, fast transient response, high precision, and a constant switching frequency. The principle of the proposed UVQC is provided in detail. The performance of the voltage quality improvement to the wind turbine is verified to be excellent with the provided experimental waveforms.

“…And the intemal capacity ratio of IEEE model 220kV side is closed initially, and after 20 seconds the LM is was assumed as constant-I (40%)+ constant-G(30%) + closed with TCR de-blocking simultaneously. This period of constant-P(30%) [4]. The dynamic analysis results showed the 20 seconds is selected to wait disappearance of transformer capacity of+/-200MVA can restore bus voltage more than 90% inrush current.…”

The they are constant active power loads and tend to absorb more capacity of the SVC is +/-200MVA. The SVC consists of two reactive power when system voltage is lower. identical SVCs of +/-lOOMVA connected to 220kV bus, and they are operated as independently or in parallel.
