Allocation of synchronous condensers for restoration of system short-circuit power [PDF]
Journal of Modern Power Systems and Clean Energy, 2017 Modern power systems, employing an increasing number of converter-based renewable energy sources (RES) and decreasing the usage of conventional power plants, are leading to lower levels of short-circuit power and rotational inertia. A solution to this is

Fault diagnosis method based on multi‐source information fusion for weak interturn short circuit in synchronous condensers [PDF]
IET Electric Power Applications, 2021 The interturn short circuit fault in rotor windings is a common fault in a synchronous condenser. Aiming at the early faults that are difficult to detect, the theory of multi‐source information fusion is applied herein for the identification of short ...

Discrimination Method of Interturn Short-Circuit and Resistive Unbalance Faults for Synchronous Condenser [PDF]
IEEE Access, 2021 In this paper, a discrimination method is proposed for the interturn short-circuit and resistive unbalance faults of the synchronous condenser. The mathematical models of the synchronous condenser are established under these two faults.

Software-Defined Virtual Synchronous Condenser
IEEE Transactions on Power SystemsSynchronous condensers (SCs) play important roles in integrating wind energy into relatively weak power grids. However, the design of SCs usually depends on specific application requirements and may not be adaptive enough to the frequently-changing grid conditions caused by the transition from conventional to renewable power generation.
