Analysis of subsynchronous resonance in power systemsZhu, Wenchun 13 June 1994 (has links)
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. / Graduation date: 1995

Analysis and control of power systems using orthogonal expansionsFernandes, Stephen Ronald 02 July 1992 (has links)
In recent years, considerable attention has been focused on the application of
orthogonal expansions to system analysis, parameter identification, model reduction
and control system design. However, little research has been done in applying their
useful properties to Power System analysis and control. This research attempts to
make some inroads in applying the so called " orthogonal expansion approach " to
analysis and control of Power systems, especially the latter.
A set of orthogonal functions commonly called Walsh functions in system
science after it's discoverer J.L. Walsh [1923] have been successfully used for
parameter identification in the presence of severe nonlinearities. The classical optimal
control problem is applied to a synchronous machine infinite bus system via the
orthogonal expansion approach and a convenient method outlined for designing PID
controllers which can achieve prespecified closed loop response characteristics. The
latter is then applied for designing a dynamic series capacitor controller for a single
machine infinite bus system. / Graduation date: 1993
