The Static Synchronous Series Compensator (SSSC) is one of the recently developed Flexible AC Transmission System (FACTS) devices. In this paper, the SSSC is realized using a 48-pulse voltage source inverter. Fuzzy logic controllers are designed to operate the SSSC in the automatic power flow control mode. The parameters of the fuzzy controllers are varied widely by a suitable choice of members...

The Static Synchronous Series Compensator (SSSC) is one of the powerful Flexible AC Transmission System (FACTS) controller recognized for power flow, power oscillation damping and improving transient stability. This paper proposes controller that is a combination of Fuzzy Logic Power Oscillations Damping (FLPOD) controller with Proportional and Integral Power Flow (PIPF) controller for SSSC to ...

1.1 General Introduction During the past two decades, the increase in electrical energy demand has presented higher requirements from the power industry. More power plants, substations, and transmission lines need to be constructed. However, the most commonly used devices in present power grid are the mechanically-controlled circuit breakers. The long switching periods and discrete operation ma...

This report concentrates on presenting transient stability and power ow models of Thyristor Controlled Reactor (TCR) and Voltage Sourced Inverter (VSI) based Flexible AC Transmission System (FACTS) Controllers. Appropriate models for voltage and angle stability studies are discussed in detail for the Static Var Compensator (SVC), the Thyristor Controlled Series Compensator (TCSC), the Static Va...

The characteristics of the distance relay are devised based on online and fault impedance. uses information to react expected state; however, integrating grid with a unified power flow controller (UPFC) might stop from fault-triggered operations, requiring altered characteristics. Building tripping parameters among critical challenges that must be addressed for transmission line relays because ...

This paper presents a proposal for a new upgrade that will incorporate power electronics experiments in the electric machines lab at Oklahoma State University (both Stillwater and Tulsa campuses). We will introduce a general lab setup which includes digital data acquisition (DAQ) and virtual instrumentation. The application of 3 inverters will be discussed with our lab setup. The installation o...

This paper proposes, an efficient variant of particle swarm optimization (PSO) to solve the multi-objective optimal reactive power flow (ORPF) based flexible AC transmission system (FACTS) using multi STATCOM Controllers by adjusting dynamically their parameters setting. Two objectives function are considered (power loss and voltage deviation) to validate the robustness of the proposed approach...

In this paper, the dual heuristic programming (DHP) optimization algorithm is applied for the design of two LOCAL nonlinear optimal neuro-controllers on a practical multi-machine power system. One neuro-controller is designed to replace the conventional linear controllers, which are the automatic voltage regulator (AVR) and speed-governor (GOV), for a synchronous generator. The other is a new e...

Back-to-back static synchronous compensator (BtBSTATCOM) consists of two back-to-back voltage-source converters (VSC) with a common DC link in a substation. This configuration extends the capabilities of conventional STATCOM that bidirectional active power transfer from one bus to another is possible. In this paper, VSCs are designed in quasi multi-pulse form in which GTOs are triggered only on...
