-
The increased need on supervision, control, and performance in modern power systems make power quality monitoring an essential requirement for utilities. Getting the present status of the power quality in the network is so vital as these data are necessary to benchmark the system. Though utilities around the world have done this type of surveys for their systems, a similar monitoring project has not been done for the Sri Lankan power network. The paper describes the power quality monitoring program carried out to represent the entire Sri Lankan Transmission network. It presents the primary selection of monitoring sites and how their results can be used for benchmarking the system. Another objective of this study is to investigate the suitability of standards such as CENELEC EN 50160 which is the first "electricity as a product" standard. ©2006 IEEE.
