Wind farm operations often involve remote interactions with off-site control rooms. This poses a challenge because every wind turbine generates a large amount of information related to running conditions and power...More
Medium-voltage (MV) distribution systems are undergoing a revolution: Gone are the days when they merely distributed power of consistent quality from some far-off generator and performed basic switching and...More
Energy storage has been a feature of electricity generation, transmission and distribution for well over a century. The introduction of the rechargeable lead acid battery in the early 1880s was later followed by pumped-hydro ......More
Smart grids gather information and reach conclusions, but to react appropriately to changes in the generating and transmission environment, the systems and the people behind them need a complete view of the network status....More
Two different designs of thyristorbased line-commutated valves have been developed by ABB: a conventional base-mounted design with support insulators standing on the floor, and another (more frequently used) design with the valve suspended from the ceiling of the valve hall ......More
Modern electricity transmission and distribution networks are undergoing dramatic changes. They have to cope with more distributed and renewable energy resources, more data from smart power equipment and meters, and more pressure to run efficiently. This all results in more work and stress for network operators......More
Aging assets, rising energy demand, and the critical need to avoid unplanned outages are challenging utilities and industries around the world. And while financial constraints are reducing maintenance budgets and investment, demand for increased return on investment is unabated....More
Industrial transformers are key elements in the processes into which they are integrated. Reliability is crucial to ensure uninterrupted operation of converters, furnaces, motors and smelters used in a variety of applications....More
Modern open-pit mining is a high-tech undertaking in decidedly hostile environments. Safe and efficient operation requires precise coordination of some of the world's largest and most expensive machines in settings characterized by punishing heat and cold as well as extreme shock and vibration....More
Asset-intensive industries face increasing pressure to improve how well they utilize and maintain their equipment. Asset health management is emerging as a critical business process due to the potentially very significant bottom-line impact of asset decisions on profitability, compliance and customer satisfaction....More
Current and voltage measurements are two key functions in the control and protection of electric power grids. Traditionally, they have been performed using so-called instrument transformers – somewhat bulky and heavy devices that can weigh up to several tons....More
Using advanced converter technology developed by abb, the world's first hvdc transmission with voltage source converters began transmitting power in 1997. This technology was introduced as hvdc light. The new transmission link ran along a 10 km route between the swedish towns of hellsjön and grängesberg. It was rated at 3 mw / ± 10 kv dc....More
Acquisition-focused ABB is chasing the "emerging markets" of utility analytics and asset management in North America, Gary Rackliffe, VP of smart grids, North America, at ABB, told us recently in an exclusive interview....More
Surge arresters are a crucial link in your power-protection system. Over time, lightning and switching surges will reduce the performance and reliability of your arresters. Watch this video to learn the most-common methods of testing your surge arresters to verify their health.
