“…Synchronous Condensers synchronous condenserss (SCs) are machines that are synchronized with the power system and operate as free spinning motors. SCs have played an important role in reactive power compensation and they have contributed to voltage stability in power systems for more than 50 years [83,84]. Currently, several TSOs have started to investigate SCs effect in mitigating the RoCoF and enhancing the frequency stability [85].…”

“…Synchronous condenser (SC) has been playing a key role in keeping voltage stability through reactive power regulation in conventional power systems for a couple of decades [8], [9], [10]. In addition, SC is an alternator that can provide inherently inertial response due to the electromagnetic coupling with the grid.…”

Toward the renewable energy era where the electricity is based 100 % on renewable energy sources, the power systems are experiencing operational challenges due to lack of short-circuit power and inertia support. This may cause a cascade failure or even a collapse of the whole system. In addressing this issue, synchronous condenser as a reborn technology which not only supports voltage regulation but also supplies inertial response and short-circuit power for the systems. This paper validates the synchronous condenser benefit at Talega substation in southern California which is equipped with a modern and advanced control technology for synchronous condensers. Based on the measurement data from phasor measurement unit (PMU), it can be concluded that synchronous condenser is a critical key for the system frequency stability improvement and short-circuit power support of renewable-based systems.

We are developing a double layer damper which will consist of a squirrel-caged warm damper and a cylindrical cold damper as a part of our 70 MW superconducting generator development project. To evaluate the characteristics of unbalance current capability, magnetic shielding and damping for rotor swing, we have constructed a 1/2 scale rotor model and conducted an experimental study. From analysis of the experimental results, we have developed design guidelines and refined our FEM magnetic field analysis technique. The main results are summerized below: (1) The squirrel-caged warm damper has sufficient capability against negative sequence current. (2) Damping characteristics can be designed to be effective near the rotor swing frequency. (3) Flux shielding at low frequencies corresponding to quick response excitation is sufficiently small so as not to prevent field flux change. (4) Magnetic field can be analyzed by the refined FEM field analysis technique which now takes into account the effects of the rotor end region by estimating the end resistance based on eddy current flow path.
