restoration process improvement in power systems with series compensated transmission lines

Fault Location in Series Compensated Transmission Lines

Due to the integration of modern technology such as electric vehicles, the emphasis is expected to shift from mechanical to electric power. Therefore, the need of increasing the power transmission capacity of the electric grid gets highlighted. Since, the construction of transmission lines is a tedious task owing to legalities, environmental impacts and high costs, the series compensated transm...

Fault Location on Compensated Transmission Lines without Current Measurement

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...

A Direct Power Controlled and Series Compensated EHV Transmission Line

This paper presents the design and analysis of a compensation method with application to a 345 kV 480 MVA three-phase transmission line. The compensator system includes a series injected voltage source converter that minimizes the resonance effects of capacitor line reactance. This creates an ability to compensate for the effects of subsynchronous resonance and thereby increase line loadability...

maximum load restoration in power systems with tcsc and svc

in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...

Improvement of Power System Condition by Placement of Flexible Alternating Current Transmission Systems devices

Flexible Alternating Current Transmission Systems (FACTS) devices have been used for several targets in power system, one of the main contributions of the devices is improving operation conditions. In this paper, two types of these devices have been placed to raise voltage profile, minimizing system loss and arising loadability. The suggested FACTS devices are: Unified Power Flow Controller (UP...
