Power compensation apparatus and method of controlling the same
A power compensation apparatus compensates for power of a power system to be allowed to transmit from at least one or more power sources to a load. The power compensation apparatus includes a first system connected to the power system to compensate for active power and reactive power of the power system, a second system connected to the first system to store power necessary for compensating for active power and reactive power, and a third system connected to the second system to generate the power to be stored in the second system.
DYNAMIC LINE RATING DETERMINATION APPARATUS AND ASSOCIATED METHOD
A dynamic line rating determination apparatus configured to control the current applied to a power line conductor by determining a dynamic maximum current rating for said power line conductor, based on measured voltage and current phase vectors taken at two temporally spaced sample times, the phase vectors including a voltage and current phase vector for each phase of electrical power carried by the power line conductor at a first and second end of the power line conductor; and determining the dynamic maximum current rating by; applying the phase vectors to a power line model to estimate the conductor temperature, applying the estimate to a thermal model to predict a steady state temperature that the power line conductor will reach, and calculate the dynamic maximum current rating based on the prediction of the steady state temperature, a power line conductor current, and a maximum temperature limitation value.

Terminal and battery charging control device and method thereof for realizing overcurrent and/or overvoltage protection
The present disclosure relates to the technical field of charging. A terminal and a battery charging control device and method are provided. The battery charging control device including a battery connector, a main control circuit and a quick charging switch circuit is adopted. During the regular charging or the quick charging, the main control circuit performs a data communication with the external power adapter via the communication interface, and obtains a charging voltage and a charging current for the battery; if the charging voltage is greater than a voltage threshold and/or the charging current is greater than a current threshold, the main control circuit sends a charging switch-off instruction, such that the controller controls the communication interface to switch off; if the charging voltage is less than or equal to the voltage threshold and the charging current is less than or equal to the current threshold, the main control circuit continues to obtain the charging voltage and the charging current.

Power line reactance module and applications
The disclosure is generally directed to reactance modules or DSRs (30) that may be mounted on a power transmission line (16) of a power transmission system (400). A DSR (30) may be configured in a bypass mode or in an injection mode (where reactance is injected into the corresponding line (16)). Multiple DSRs (30) installed on a power line section (18) define an array (410) and have a dedicated controller (440). Such an array (410) and controller (440) may be installed on a number of different power line sections (18). The controller (440) for each array (410) may communicate with a DSR server (420), which in turn may communicate with a utility-side control system (430). Each DSR (30) may incorporate one or more features directed to core (50) configurations and assembly, communications, modal configuration control, fault protection, EMI shielding, DSR (30) assembly, and DSR (30) installation.
