High voltage direct current (HVDC) links are interties, characterized by good controllability, large adjustable capacity and fast responses, and have inherent advantage in damping interarea oscillations over power system stabilizers (PSS) and flexible alternating current transmission systems (FACTS). In this paper, a systematic and practical means to design the multiple HVDC damping control system,...
The interconnection project between Turkish grid and the ENTSO-E CESA system is almost finished. According to feasibility analysis based on computer simulations, inter-area oscillations around ~0.15 Hz is expected once the interconnection is established. Unless countermeasures are taken, these oscillations could grow to dangerous amounts which will result in disconnection of Turkish grid from the...
In this paper, using a new solution method, the phasor simulation, a model of two-machine power system with static var compensators (SVC) and power system stabilizers (PSS) is built. By this system model, the transient stability analysis of this two-machine power system when single-phase fault and 3-phase fault is simulated. The result shows that the phasor solution method can reduce simulation time...
On 24th September, 2006, a severe disturbance occurred on the National Grid System of Pakistan which caused cascading outages of transmission lines and generating stations that ultimately led to system wide collapse/blackout. This major blackout was one of the worst power system failures of WAPDA, the main electric utility of Pakistan. This paper provides an insight of the investigations to identify...
Based on the analysis of the control mechanism as well as the evaluation upon the control effect of power system stabilizers (PSS) and HVDC damping modulation, in specific to the AC/DC hybrid grid with multi-HVDC inverters electrically adjacent in the same AC system, the coordinated control strategy between PSS and HVDC damping modulation for the damping of inter-area power swings is put forward....
