The voltage flicker is main factor influencing the power quality and SVC is well-proven solution. The flicker reduction requires very short response time, according to the relation analysis between flicker improvement factor and response time. SVC has a fast open-loop control function to achieve effective voltage support. The fast algorithm of flicker reduction is presented here based on synchr...

The power quality (PQ) issue is get new measurement because of power system rebuilding and moving pattern towards distributed generation. PQ comprises of an expansive number of unsettling influences, for example, voltage sags, swells, harmonics, notch, flicker and so forth. To conquer these issues identified with the PQ, FACTS gadgets are presented. A distribution static compensator (D-STATCOM)...

One of the main challenges future in utility sector is constructing new transmission line corridor. This due to fact that land compensation cost associated with expansion a corridor becomes very expensive and also power efficency low. In addition that, high carbon emission, which major challenge world right now, related additional conventional energy-based generation meet dramatically increased...

Maximum power transfer capability in the transmission line is the utmost important consideration in power systems. VAR Compensator (SVC) and Static Synchronous Compensator (STATCOM) are important devices in FACTS family, and is widely recognized as an effective and economical means to solve the power system stability problem. SVC and STATCOM are used as shunt in transmission system. In the pres...

This paper deals with the solution of the issue of exceeding the permissible levels for long-term flicker effect Plt in industrial distribution systems. Flicker effect in distribution systems is often exceeded as a result of the connection of electric arc furnaces, which exhibits high variable electrical power in-take. The article shows the benefits of measures on the steel plants, the distribu...

This paper presents a survey on key issue, challenges and opportunities of power quality problems (PQ) such as transients, instantaneous (interruption, swell & sag), long duration variations (interruption, under voltage, over voltage), harmonics, voltage unbalance, voltage fluctuation, power frequency variations, power factor of system, and waveform distortion such as current and voltage in the...

This paper presents the introduction of various FACTS controllers such as SVC, TCSC, TCPAR or TCPAT, SSSC, STATCOM, UPFC, IPFC, GUPFC, HPFC for operation, control, planning & protection from different performance point of view such as increased the loadability, improve the voltage profile, minimize the active power losses, increased the available transfer capacity, enhance the transient and ste...

Renewable energy sources are alternative energy source, can bring new challenges when it is connected to the power grid. Generated power from wind energy system is always fluctuating due to the fluctuations in the wind. According to the guidelines specified in IEC61400 standard (International Electro-technical Commission) provides some norms and measurements. The performance of the wind turbine...

Nowadays, the energy crisis has forced the need to recover the energy which is normally wasted in industrial processes. Gas pressure reducing process in city or power plant gas stations is one of these processes in which the energy is wasted. This work is done by turbo-expanders in parallel with gas regulating valves. In electrical industry, these devices drive generators to produce electrical ...
