Dynamic Parameter Tuning Based on System Transient Response

Dr. Farrokh Shokooh & Dr. JJ Dai of Operation Technology, Inc.

Knowledge of a synchronous machine and its associated control system dynamic parameters is essential to power system transient stability simulation studies. These parameters include synchronous machine impedances and time constants on d and q axis, machine inertial and damping coefficients, generator prime mover and governor parameters, excitation system and AVR parameters, Power System Stabilizer (PSS) parameters, motor load characteristic curve parameters, etc. Accuracy in these parameters directly affects credibility of the simulation results. This tutorial starts with descriptions of dynamic behavior of some common transfer functions used in dynamic modeling with respect to their parameters. A standard synchronous generator dynamic model and its response to a disturbance as a function of model parameters are discussed and illustrated graphically next. It is followed by a real system project example, which involves a generator start-up and motor re-start. Effectiveness of the dynamic parameter tuning technique is demonstrated by comparison between the field measured data and transient stability simulation results with tuned parameters. A very close correlation between two sets of data is achieved. More examples of using dynamic parameter tuning to obtain a set of machine parameters with confidence are presented by a diesel generator load acceptance test and a short-circuit test. In all examples, machine parameters are tuned to successfully match the field testing results both in RMS values and instantaneous values.

#2 - Thursday May 10th 8AM - 11:30AM, 1PM - 4:30PM

Comprehensive Design Of Electrical Installations Integrating System
Configuration And Operational Safety Aspects

Rasheek Rifaat of Jacobs Engineering Group Inc., Giuseppe Parise, Professor
of the University of Rome, Erling Hesla, consultant

The objective of the tutorial is to provide participants of industrial electrical system engineers, designers and operators with a comprehensive understanding of present and developing concepts in operational procedures for industrial electrical power systems.
The tutorial deals with personal safety during system operation and maintenance and includes detailed discussion on important LO/TO procedures, especially for the not automatic operations. It allows constructive comparison between European and North American Practices.
The high availability and integrity requirement of all the loads, or part of them, is satisfied by means of a system structure that increases the complexity level with the inclusion of main, alternate, stand-by and emergency sources, as well as with the diverse applications of varying switch-able configurations.

#3 - Friday May 11th 8AM - 11:30AM

Electrical Arc Hazard Committee - Electrical Safety and Arc Flash in the
Industrial & Commercial environment

Daniel Roberts of Schneider Electric

Governments have established minimum standards of safety care through occupational health and safety legislation. However, legislation is seldom specific enough to provide guidance as to how to meet those standards of care. NFPA 70E Electrical Safety in the Workplace and the soon to be released parallel Canadian document CSA Z462 provides the how-to knowledge for electrical safety.
This tutorial will discuss the development and current state of these two standards, including some of the challenges facing the committees involved in the current revision cycle. The tutorial will explain the key safe work practices contained in these documents: qualifying the electrical worker, job planning, establishing an electrical safety program, creating an electrically safe work condition, shock and arc flash hazard analysis, shock and arc flash protection boundaries. These work practices will be framed in the context of occupational health and safety legislation.

#4 - Friday May 11th 1PM - 4:30PM

Application Guidelines on Current Transformer (CT) and Potential
Transformers (PT) for both Metering and Protection

Dr. PK Sen, Professor of the Colorado School of Mines

This half-a-day short course has been designed for junior and senior power system design engineers in utilities and with consultants, undergraduate and graduate students in electric power concentration, managers and plant technical personnel and others interested in the subject. It is assumed that participants have some rudimentary basic and broad knowledge of electric power systems design and protection engineering. Practical experience is preferable, but not required. One of the main objectives of this course is to focus on the design, selection and applications of CT's and PT's as applied to power systems protection and metering at all voltage (distribution and transmission) levels. Extensive handouts will be provided in the class. Numerical examples will be discussed to enhance the understandings.
