Enhancing Power Quality for Bulgarian Railways Reactive Power Compensator PQC-STATCON Helps Ensure Grid Compliance

Reference case- Railways Enhancing power quality for Bulgarian Railways Reactive power compensator PQC-STATCON helps ensure grid compliance

Reactive power compensators connect diverse geographies – from Customer problem statement from ABB, installed in five traction the snow-capped Balkan mountains to substations across Bulgaria have the sunny Black Sea coast, from the Large varying non-linear loads are an improved power quality across the bustling state capital Sofia to culture inherent feature of electrical railway rail network, bringing further benefits hub Plovdiv, and from Balkan Serbia to traction systems. Since the load such as increased availability of the Mediterranean Greece. changes dynamically and constantly, the supply network, higher reliability and traction power supply system draws a improved energy efficiency. The National Railway Infrastructure high amount of reactive power resulting Company (NRIC), responsible for the in low power factor affecting power The Bulgarian State Railways, founded smooth operation and maintenance quality. Poor power quality is not only in 1888, are among the oldest of this railway infrastructure and the harmful to the traction system itself, but rail networks in Europe. Providing electrical power that supports it, was also prone to spreading through the passenger and freight services, they facing power quality challenges across supply grid and can cause disturbances cover more than 4,200 kilometers and the network. to other users on the same grid. It also results in non-compliance to grid codes, leading to financial impact in the form of penalties. www.abb.co.in Fax: +91-80-22949339Email:[email protected] Phone: +91-80-22949334/93919330 Bangalore India -560058,Karnataka, Peenya IndustrialArea, 14th Cross, 4thPhase, Plot no485/6, LV capacitorsPowerQualitySolutions ABB Limited substations.
