AC Power Monitoring System

Shunyata Denali AC Power Conditioning System

That doctor, whose days were filled with analyzing and interpreting the tiny electrical signals emitted by the heart, spent his evenings enjoying music through a high-end system. Discovering that Shunyata’s Triton AC conditioner improved the low-level resolution of his audio system, he surmised that the Triton may allow him to more clearly see the heart’s tiny electrical signals in a clinical s...

Dual AC-Input Power System Architectures

Power systems for data-processing and communication equipment used in mission-critical applications that require high system availability must be implemented with fault-tolerant architectures. Generally, these fault-tolerant power architectures require that the power supplies built into data-processing/communication equipment are capable of operating from two different ac power sources. In this...

Power System Stability Enhancement by Simultaneous AC-DC Power Transmission

This paper presents the concept of simultaneous ac-dc power transmission. Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits due to this instability occurs in the power system. It is difficult to load long extra high voltage (EHV) ac lines to their thermal limits as a sufficient margin is kept against transient instability. With the model proposed in this thesis, it...

A Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter

Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
