Outdoor Hydrogen-Ventilated Synchronous Condensers
Transactions of the American Institute of Electrical Engineers, 1929Hydrogen is an excellent cooling medium for high-speed rotating electrical machinery. When it is substituted for air, a machine can be operated at a higher load with the same temperature rise and the windage loss is decreased to one-twelfth. Furthermore, since no oxidation can take place in this type of machine, the life of the insulation is increased ...

New synchronous condensers for Jeju Island
2012 IEEE Power and Energy Society General Meeting, 2012Jeju Island has long been served by an HVDC link to the main Korean peninsula. A second HVDC link will soon be added and once this is complete, the original HVDC link will also be refurbished. Since its original installation, synchronous condensers have provided reactive power support to the HVDC converters. As part of the overall upgrades taking place

Impact of Synchronous Condenser on Sub/Super-Synchronous Oscillations in Wind Farms
IEEE Transactions on Power Delivery, 2021Sub/Super-synchronous oscillations have occurred in wind farms consisting of doubly-fed induction generators (DFIGs) or permanent magnet synchronous generators (PMSGs). This paper investigates the impact of synchronous condenser (SC) on sub/super-synchronous oscillations in wind farms with different types of generator and compares it with STATCOM ...

Grid-connection Time Forecast of Synchronous Condensers
2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE), 2020With the rapid development of UHVDC power transmission, synchronous condensers with dynamic reactive power compensation capability begin to be applied on a large scale. In view of the grid-connection problem of synchronous condensers, based on the improvement of traditional phase-angle difference time function, this paper analyses the influence of ...

A large-scale PWM solid-state synchronous condenser
IEEE Transactions on Industry Applications, 1992The description, steady-state analysis, and control design of a microcontroller-based large-scale pulse-width modulated solid-state synchronous condenser (PWM-SSSC) for reactive power compensation is presented. The key feature of the proposed compensator is the low switching frequency of the PWM pattern, which allows the utilization of high-power GTO ...
