This book presents comprehensive mathematical models of turbine-generators, HVDC and FACTS controllers, and small signal analysis of SSR. The emphasis is on the analysis using linearized models. Both damping torque and eigenvalue analysis are covered. Also included are the basic concepts of SSR interactions with fixed series compensation, PSS, HVDC, and FACTS controllers. Timely treatment has been given to the development of electrical analogue for the rotor system, the derivation of the network equations based on circuit topology and immittance functions using D-Q variables. The material is supported by several illustrative examples and case studies based on IEEE benchmark models. Analysis of Subsynchronous Resonance in Power Systems is an invaluable reference work for power systems researchers, system planners, and designers.

Three aspects of Subsynchronous Resonance (SSR) related problems in power systems are addressed in this dissertation which aims at contributing to a better understanding of these problems. Subsynchronous Resonance (SSR) problems in series compensated steam-turbine power systems co-exist with the beneficial effects provided by the series capacitors. Since the early 1930s, numerous researchers have addressed issues relating to these problems. The development of a generalized frequency scan method for analyzing SSR in a Single-Machine Infinite-Bus (SMIB) power system equipped with fixed series capacitor compensation is presented. This method overcomes shortcomings present in the traditional frequency scan technique which is widely used in power system analysis. It has been noticed that there are nonlinear dynamic phenomena in power systems which can not be explained by linear system theory. This includes limited oscillations in a power system when it experiences SSR at a frequency close to one of the system modes. The phenomenon can be explained by Hopf bifurcations. This dissertation presents an analysis for a high dimensional model of a SMIB power system equipped with fixed series capacitor compensation. The results obtained can lead to a more precise understanding of this phenomenon than those available to date which use perturbation methods and highly simplified second-order power system models. Compared with fixed series capacitor compensation in power systems, the newly developed Thyristor Controlled Series Compensation (TCSC) scheme has some well known advantages with regard to flexible power system control. It has been noted that vernier mode TCSC operation can provide for SSR mitigation. In this thesis, such beneficial effect is demonstrated and analyzed for a simplified North-Western American Power System (NWAPS) model, based on EMTP simulations. Issues relating to modelling and simulation of power system and TCSC are addressed.

This relevant and timely thesis presents the pioneering use of risk-based assessment tools to analyse the interaction between electrical and mechanical systems in mixed AC/DC power networks at subsynchronous frequencies. It also discusses assessing the effect of uncertainties in the mechanical parameters of a turbine generator on SSR in a meshed network with both symmetrical and asymmetrical compensation systems. The research presented has resulted in 12 publications including three top international journal papers (IEEE Transactions on Power Systems) and nine international conference publications, including two award-winning papers.

This book provides a systematic introduction to power system sub/super-synchronous oscillations caused by grid-connected wind power generation. The authors look at why oscillations occur and present methods for examining the risk of oscillations. Coverage includes state-space model based analysis and impedance model based analysis, which are the two main methods for examining the power system sub/super-synchronous oscillations. In addition, new methods for examining oscillations in wind farms are proposed. Analysis of Power System Sub/Super-Synchronous Oscillations Caused by Grid-connected Wind Power Generation provides researchers and students with a single-volume introduction to the subject and will be a valuable professional reference for practicing engineers looking for solutions to oscillation problems.
