3.3 The First Investigations and Analysis
A review of existing transmission system studies was performed in each of the individual working groups as an initial step prior to the technical and organisational investigations. The IPS/UPS gave a general overview of their principle structure, key figures and the global operational control behaviour. This was presented in an IPS/UPS System Survey which was finalised in February 2006.
In parallel to the data acquisition process, the installation of a Wide Area Measurement System (WAMS) – similar to the one operating in the UCTE – was initiated in the IPS/UPS synchronous area. This transient measurement system was a prerequisite for the validation of the dynamic simulation models. One was able from early 2007, to observe the dynamic system behaviour of the whole synchronous IPS/UPS area and receive measurements, for example, following disturbances in the grid. Some 26 measurement devices had been installed in the IPS/UPS up to April 2008. Around 50 measurement devices are currently installed in the UCTE synchronously operating systems.
In order to define the necessary technical specifications, a Technical Glossary was prepared which was also used as a basis for common communication within the study.
