Thursday, 4 July, 10:00 a.m. – 12:00 noontime, Room S-101, SERD Building: ‘Hopf Bifurcation Control and Indices for Power System with Interacting Generator and FACTS Controllers’ Seminar.

The seminar will be conducted by Dr. Mithulananthan Nadarajah, Dept. of Electrical and Computer Engineering, University of Waterloo, Ontario, Canada


Power system oscillations, especially electromechanical oscillations, have been a major concern in power system planning and operation. Given the characteristics and nature of these oscillations, these problems can be studied well using Hopf bifurcation theory, which describes the onset of an oscillatory problem in nonlinear systems.

This research work presents two indices to predict and detect oscillatory problem in power systems using Hopf bifurcations; one of them is preferred as an on-line operational tool due to its higher computational speed. Application of these indices on several test power systems, including the IEEE 50-machines test system, is also included to demonstrate the usefulness of the indices. Simulation results indicate that the indices are smooth and fairly linear with respect to the loading factor of the system.

It also clearly demonstrates the direct association between electromechanical oscillations and Hopf bifurcations in power systems. The amelioration of the oscillation problem or Hopf bifurcation from the generator side, using PSS controllers, and from the transmission side, using FACTS controllers, is studied in detail. A new placement technique for a shunt-FACTS controller for the purpose of oscillation damping is also proposed.

The increasing trend in the number of FACTS controllers used in power systems could lead to some undesirable interactions between FACTS and power system controllers or among FACTS controllers. The importance of and tools needed to study this problem are demonstrated in a test system through the analysis of a negative interaction leading to an oscillatory unstable condition.

Tuesday, 9 July 2002, 2:30-3:30 p.m. in room E206, SERD Building: The School of Environment, Resources and Development, UEEM Program will organize a special lecture on ‘Surfactant-based Microemulsion Systems for Soil Remediation and Solvent Replacement: From Concept to Application.’ The lecture will be conducted by Prof. D. A. Sabatini, Sun Oil Company Chair and Associate Director, The Institute for Applied Surfactant Research, The University of Oklahoma, USA


Soil and aquifer remediation is frequently limited by contaminants strongly sorbed to and/or capillary-bound in the soil. Surfactant-enhanced soil remediation is an innovative technology for overcoming these limitations and thus expediting soil cleanup. Petroleum hydrocarbons and chlorinated solvents are common contaminants in soil and aquifer systems. Remediation of these hydrocarbons can be expedited by enhanced solubilization, using surfactant micellar systems, or by physical displacement (mobilization), resulting from ultra-low interfacial tension, middle phase microemulsion systems. For chlorinated solvents, vertical migration concerns limit the use of middle phase microemulsions – for this application we utilize a hybrid system (super-solubilization), which maximizes the solubility enhancement while minimizing the potential for vertical migration. Economic analyses demonstrate that maximizing solubility enhancement, minimizing surfactant losses and reusing the surfactant stream are critical to the viability of the solubilization and mobilization technologies. This presentation will discuss each of these fundamental issues, with an emphasis on surfactant properties critical to success. Our group has conducted more than ten field studies to date; select results will be presented to demonstrate how we have successfully addressed each of the critical areas mentioned above. Results from these field studies demonstrate the viability and robustness of this technology for a wide range of contaminant matrices and geological settings, and illustrate the exciting potential of this innovative technology.

18 – 19 July 2002: ‘Assessment and Remediation of Contaminated Sites’

The Asian Center for Soil Improvement and Geosynthetics (ACSIG) of the School of Civil Engineering (SCE), Asian Institute of Technology (AIT) will be conducting a Seminar on Geoenvironmental Engineering from 18 to 19 July 2002.
