Research on the Audible Noise Spectrum Characteristics of Typical AC Bundled Conductors in High‐Altitude Areas at 4300 m

High Voltage, EarlyView.
ABSTRACT The low pressure in high‐altitude areas exacerbates the issue of audible noise (AN) caused by intense corona discharge on the conductor surface. This problem is a critical factor in the structural design and conductor selection for extra‐high‐voltage and ultrahigh‐voltage (UHV) AC transmission lines.

Experimental Study on Disintegration Characteristics of Water Droplets in Icicle‐Flat Plate Gap Beyond Critical Discharge Voltage

High Voltage, EarlyView.
ABSTRACT The disintegration behaviour of ice‐melting droplets aggravates the discharge risk of ice‐covered insulators and the disintegration characteristics of droplets at applied voltages exceeding the critical discharge voltage lack in‐depth study.

A Control Strategy for Variable Speed Condenser Based on Doubly‐Fed Machine

IET Smart Energy Systems, EarlyView.
This paper proposes a variable speed condenser (VSC) control strategy based on a doubly fed machine. It can be installed in PV stations and wind farms to enhance the grid‐connection performance of renewable energy power plants. ABSTRACT The lack of active power support capability in power systems with large‐scale renewable energy integration has become

Flap Anatomies and Victorian Veils: Penetrating the Female Reproductive Interior

Gender &History, EarlyView.
ABSTRACT This article examines the reappearance in the early nineteenth century of anatomical flapbooks in the context of obstetrical education in Britain, America and France. It asks why liftable paper flaps were reintroduced at this time after their disappearance from medical atlases in the eighteenth century.

Rent control, rent overcharge, and racial disparity

Real Estate Economics, EarlyView.
Abstract Rent control policies have gained renewed legislative momentum in the United States, but are rent‐regulated landlords adhering to these policies? Answering this question is critical to understanding the policy's impact. Using a unique panel data set from the New York City Housing and Vacancy Survey (NYCHVS), we investigate noncompliance with ...
