2009-03 Design, installation and application of Phase Measuring Units (PMUs)
October 5-6, 2009


The objective of this course is to give to participants an introduction to Synchronized Measurement technology (SMT) and a good hands-on experience on the use of Phasor Measuring Units (PMU’s). The course will cover the design, installation and application of PMU’s.

In this course the following issues will be addressed:

• Syncronized Measurement Technology (SMT)
• Phasor Measurements Units (PMU)
• Installation of PMU’s
• Applications of various wide area monitoring, protection and control schemes (WAMPAC)
• Experiences of using WAM systems
• Real time monitoring of a Power Plant Control System

There is an increasing interest in wide area monitoring (WAMS) and control (WAMC) all over the world. A few installations cover huge areas of power systems, but most are concentrated in a critical area or one transmission corridor only.

A number of transmission system operators have just started to explore this technology and getting familiar with its use based on small installations. Phase angle and oscillation monitoring are obvious and the most commonly used applications. Voltage stability and thermal limit applications are used in some limited number of cases. The offline analysis of data plays a significant role for improved dynamic system models based on comparisons of simulations with recorded events. The integration of PMU data into the State Estimation is widely expected.

From the wide area perspective, three application areas can be expected.

First is the further spread out of slow secondary voltage control applications based on conventional technologies.
Second is the WAMS for oscillations, voltage stability or thermal limitations.
Third is Wide Area Protection, especially for transient stability.

For practical implementation, WAMC, there are some aspects which have to be considered carefully. The whole system lies on the time synchronized phasor measurements technology, taking place in Phase Measuring Units (PMUs).

The future power plant monitoring will cover two different user groups. The focus is on contractual system services for the Transmission System Operators which have to be verifiable at any time. Additional process information is desired by the power plant operator such as flow rate, position measurement, opening of the guide-vane system and current and voltage excitation.

This requires that the measured data and thus all channels can be archived with chronological synchronism and in high resolution.


Prof. John Eli Nielsen (
John Eli Nielsen was born in Denmark 1944. He received his M.Sc.EE. degree in electrical engineering from The Technical University of Denmark in 1974 and his Industrial PhD degree in 1976. He has been working for the transmission system operator in Denmark for 25 years. Currently, he is working for the Technical University of Denmark as an associate professor. His experience lies in the area of planning and operation of power systems. He is a member of IEEE and has for many years been the Danish representative in CIGRE Study Committee 39 – Power System and Control.

Assist. Prof. Rodrigo Garcia-Valle (
Rodrigo Garcia-Valle was born in Mexico. He received the electrical engineering degree from the National Polytechnic Institute of Mexico, in 2001, the M.Sc. degree from CINVESTAV, Guadalajara, Mexico, in 2003 and obtained his Ph.D. degree from the University of Glasgow, U.K., in 2007. In 2008, he was granted with the Hans Christened Ørsted Award at the Centre for Electric Technology(CET) by the Technical University of Denmark to carry out postdoctoral research activities. Since 2009 he holds the position as Assistant Professor. His research interests are dynamics, stability and control of electric power systems; artificial intelligence techniques; renewable energy integration; and modelling and simulation of FACTS and custom power controllers. He is an IEEE, IET and CIGRE member.
