Croatian Academic Research Wide Area Monitoring System – CARWAMS

Paper describes start-up of Croatian Academic Research Wide Area Monitoring System (CARWAMS), which is intended to support involvement of small R&D teams into fast developing synchronized measurement technology (SMT). Low voltage synchrophasors are collected by platform called WAMSTER, including handheld Phasor Measurement Units (PMUs) and GPRS data transfer to a dedicated served. Measurements are available on-line. CARWAMS uses previously developed Phasor Data Concentrator (PDC) with added pseudo real time monitoring applications such as angle and frequency instability. Archived measurements and calculated results are used for post mortem analysis and further development of applications.
