Patent
Collection and transmission system
TL;DR: In this paper, a collection and transmission system (10) includes: a system direct current (DC) link (12) configured for carrying power from a source (13) to a grid (16); and alternating current (AC) to DC power converter modules (19, 119, 219, 319) coupled in series to the system DC link on a source side, each power converter module configured for being coupled to one or more sources (114, 214, 314, 414).
Patent
Wind park, method of correcting voltage imbalances, and wind turbine
TL;DR: In this paper, a wind park, a method of correcting voltage imbalances, and a wind turbine are provided, where a transformer is coupled between the at least one wind turbine and a power grid.
Patent
Method and system for control and protection of direct current subsea power systems
TL;DR: In this article, a high-voltage DC (HVDC) power system is described, which includes a plurality of sending-end (SE) modules coupled in electrical series and divided into at least two groups (111, 113) that operate independently with respect to an electrical ground.
Patent
Airflow control apparatus
TL;DR: In this paper, an apparatus for controlling an airflow to a boiler or a boiler and maintaining a desired quantity of air is described, which comprises a controller for generating a control signal of a level corresponding to a required airflow, a variable-frequency power supply for producing an output of a frequency corresponding to the control signal level so as to drive a ventilation-actuating motor, and means for detecting any deviation of the controller signal level from a predetermined range and retaining the frequency of the motor-driving output at a proper value, whereby the airflow is maintained at or above a preset value
Patent
Static converter station for high voltage
TL;DR: In this article, a converter station for high voltage is formed of a plurality of static converters with a direct current side directed in series each converter is a full-wave rectifier bridge provided with a control device.
