“…It can be concluded that the power factor is inversely proportional to apparent power. Consequently, any increase in power factors results in a decrease in apparent power, whereas a reduction of the power factor causes an increase in the apparent power [18][19][20][21][22][23].…”

A power system suffers from losses that can cause tragic consequences. Reactive power presence in the power system increases system losses delivered power quality and distorted the voltage. As a result, many studies are concerned with reactive power compensation. The necessity of balancing resistive power generation and absorption throughout a power system gave birth to many devices used for reactive power compensation. Static Var Compensators are hunt devices used for the generation or absorption of reactive power as desired. SVCs provide fast and smooth compensation and power factor correction. In this paper, a Fuzzified Static Var Compensator consists of Thyristor Controlled Reactor (TCR) branch and Thyristor Switched Capacitors branches for reactive power compensation and power factor correction at the load side is presented. The system is simulated using Simulink using a group of blocks and equations for measuring power factor, determining the weightage by which the power factor is improved, determining the firing angle of TCR branch, and capacitor configuration of TSC branches. Furthermore, a hardware prototype is designed and implemented with its associated software; it includes a smart meter build-up for power monitoring, which displays voltage, current, real power, reactive power and power factor and SVC branches with TRIAC as the power switching device. Lastly, static and dynamic loads are used to test the system's capability in providing fast response and compensation. The simulation results illustrated the proposed system's capability and responsiveness in compensating the reactive power and correcting the power factor. It also highlighted the proportional relation between reactive power presence and the increased cost in electricity bills. The proposed smart meter and SVC prototypes proved their capabilities in giving accurate measurement and monitoring and sending the data to the graphical user interface through ZigBee communication and power factor correction. Reactive power presence is an undesired event that affects the equipment and connected consumers of a power system. Therefore, fast and smooth compensation for reactive power became a matter of concern to utility companies, power consumers and manufacturers. Therefore, the use of compensating devices is of much importance as they can increase power capacity, regulate the voltage and improve the power system performance.

“…Широко используемым способом компенсации реактивных компонент токов является установка статических компенсаторов, а именно, батарей конденсаторов (БК) с тиристорным переключением и тиристорно-управляемых реакторов (ТУР). Однако они имеют ряд недостатков, что ограничивает их использование: батареи конденсаторов не обеспечивают плавность управления величиной РМ и чувствительны к наличию компонент неосновной частоты в приложенном напряжении, а работа ТУР приводит к генерации токов высших гармоник [3], [4]. Кроме того, установка статических компенсаторов вызывает проблемы, связанные с возможностью возникновениея резонансов токов и напряжений.…”

“…The advantage of our novel module is cost reduction and THD reduction due to the use of only one control signal line. Authors of paper [6], [7] and [8] showed simulation of FC-TCR compensation in single phase AC system using Dual-Thyristor for TCR branch. They have elaborated in detail, the variation of the inductor current waveforms and THD noise in these papers.…”

The concept of replacing mechanical switcher using Solid State Devices (SSR) as the medium of relaying high power AC load has already been recommended five decades ago using Dual Thyristor or Triac. The rapid growth in SSR field has now resulted in using dual IGBTs, dual JFETs, dual MOSFETs or dual HEMTs semiconductor devices to control high powered AC loads. One of the drawbacks of all the systems above is that they all using two semiconductor devices to operate for both half cycle of the single phase AC waveform, with either anti-parallel or anti series-arrangement incorporated. We have modeled a novel SSR, using only one MOSFET semiconductor device with a new SSR module packaging. This novel Uni-MOSFET SSR is capable of operating on both half cycles of an AC waveform and eliminating problems associated with dual semiconductor SSR system. Moreover, in this paper we have explained the simulations proving that the Uni-MOSFET SSR is able to control resistive load and able to compensate capacitive and inductive as a SVC, which is as good as its predecessor the Dual-Thyristor SSR. The draw back would be the complexity of the control signals of the Uni-MOSFET SSR for TCR but we have managed to simplify using equations. Our novel SSR is cost efficient, low noise and works well as a load switcher, circuit breaker or compensation switch for single phase electrical network system.
