A separation of the reactions in photosynthesis by means of intermittent light [PDF]

open access: yes, 1932
Experiments on photosynthesis in intermittent light have been made on two occasions. Brown and Escombe, in 1905, made use of a rotating sector to study the effect of light intensity on the photosynthesis of leaves.

SLAC synchronous condenser [PDF]

open access: yesProceedings Particle Accelerator Conference, 2002
A synchronous condenser is a synchronous machine that generates reactive power that leads real power by 90 degrees in phase. The leading reactive power generated by the condenser offsets or cancels the normal lagging reactive power consumed by inductive and nonlinear loads at the accelerator complex. The quality of SLAC's utility power is improved with

Dynamic Behaviors and Protection Strategy of Synchronous Condenser Integrated Power System Under Non-Full Phase Fault Conditions

open access: yesIEEE Access, 2019
When a synchronous condenser connected power network encounters a non-full phase fault, the amplitude of the stator current is severely suppressed by the magnetic field generated inside the synchronous condenser, in which the sensitivity of failure ...

Characteristics Analysis of Field Winding Inter-Turn Short-Circuit Fault for Large-Capacity Synchronous Condenser Based on Stator Winding Asymmetric Branch Current

open access: yesIEEE Access, 2023
The early inter-turn short-circuit fault of field winding (ISFF) occurs between adjacent strands in a single rotor slot, which is a significant safety hazard in the transient operation of the large-capacity synchronous condenser.

Optimal security-constrained power scheduling by Benders decomposition [PDF]

open access: yes, 2006
This paper presents a Benders decomposition approach to determine the optimal day-ahead power scheduling in a pool-organized power system, taking into account dispatch, network and security constraints.

Optimization and Transient Analysis of Distributed Asynchronous Condenser

open access: yesIEEE Access, 2022
After the high proportion of new energy is connected, the decrease of the proportion of synchronous machine in power system will cause a series of stability hazards, such as the lack of inertia.
