Today, with attention to increase in sensitive electrical equipments application in distribution networks and their susceptibility to the power quality deficiencies, the protection necessity of sensitive loads against undesirable effects of these disturbances are in focus. So, in this paper voltage sag deficiency and Dynamic Voltage Restorer (DVR) would be introduced as the most prevalent power...

Generation systems, using renewable sources, are becoming increasingly popular due to the need for increased use of electricity. Currently, renewables sources have a role to cooperate with conventional generation, due to the system limitation in delivering the required power, the need for reduction of unwanted effects from sources that use fossil fuels (pollution) and the difficulty of building...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...

Abstract-This paper presents a comprehensive simulation study of PI Controlled Three phase Series active power filter to improve power quality. The series active power filter employs a method for the reference compensation current based on Fast Fourier Transform Passive, L-C filters have disadvantage of fixed compensation and not fit for fast varying condition while by using auto tuned active p...

The Talk Test (TT) is a simple technique for prescribing exercise training intensity, based on the ability to ‘speak comfortably’ after reciting a standard speech provoking stimulus. This study compares the length of the speech provoking stimulus on power output (PO) at standard TT speech comfort markers: last positive (LP), equivocal (EQ), negative (NEG), in relation to objective markers of ex...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Reactive power compensation is presented in this paper as an additional function to the three phase active ac/dc voltage source converter for neighboring inductive loads. The main function of this converter is to operate as controlled DC power supp...

In the practice of watershed ecological compensation, due to inconsistency between interests economic development and objectives protection, there are typical game characteristics among relevant stakeholders. Taking compensation Henan Shaanxi in Yellow River Basin as an example, this paper constructs evolutionary model, obtains external conditions for various stakeholders achieve stable coopera...
