This paper evaluates the impact of dynamic loads (induction motors) on the damping of Subsynchronous Resonance (SSR) based on load location and aggregate load inertia for the IEEE 68 bus network simulated in DIgSILENT. The severity of SSR oscillations is shown to increase in the presence of Subsynchronous Resonance Load Interactions (SSRLI), whereby dynamic loads may contribute towards negative damping...
Major incidents of dangerous Subsynchronous Resonance (SSR) have been caused by the loss of one or more lines causing the generator to come radial or partially radial with the series capacitor. Identification of such lines in a meshed multi-compensated power network is not possible through mere topological inspection. The paper presents a methodology for identifying Critical lines that may be hidden...
This paper evaluates the impact of load dynamics on torsional interactions by considering a mix of static and dynamic loads aggregated at the bulk transmission level. This is essential to investigate the importance of detailed load modelling for subsynchronous resonance (SSR) studies to accurately assess damping contribution and capture system dynamics. SSR interaction with dynamic loads is investigated...
This paper presents a simple algorithm for calculation of simultaneous faults.i.e. Series and parallel faults in power system. The objective of this paper is fault calculation which provides current at fault locations as well as the current through each branch and voltage at each bus; this helps to design a good protective scheme which gives compressive and pragmatic fault analysis. The most important...
The creation of a suitable wide area monitoring system (WAMS) is widely recognized as an essential aspect of delivering a power system that will be secure, efficient and sustainable for the foreseeable future. In Great Britain (GB), the deployment of the first WAMS to monitor the entire power system in real time was the responsibility of the visualization of real time system dynamics using enhanced...
The creation of a Wide Area Monitoring System (WAMS) has been established as an effective solution for many of the challenges faced by modern power systems. However, the complexity and cost of a WAMS means that it is not simple to determine its optimal nature or to justify the use of customer money to create it. VISOR is an innovation project in Great Britain (GB) that, through collaboration between...
