摘要： In aspects, the invention provides a method for connecting a first subsystem of a multi-phase electrical power system with a second subsystem of the multi-phase electrical power system. The second subsystem includes a voltage of time-varying frequency. The method includes calculating, by an Intelligent Electronic Device, an instantaneous angle of separation between a voltage of the first subsystem and the voltage of the second subsystem, determining, by the Intelligent Electronic Device, a synchronization time, and operating, by the Intelligent Electronic Device, at least one switching device for connecting the first subsystem with the second subsystem based on the synchronization time. Determining the synchronization time includes compensating for time-varying frequency of the voltage of the second subsystem.

摘要： The present invention relates to a multilevel current source converter (CSC) 5 for controlling electrical power transmission in a high voltage direct current (HVDC) transmission system 1. The CSC comprises: an alternating current (AC) side 20 for input/output of AC to/from the CSC; a direct current (DC) side 21 for input/output of DC to/from the CSC; and a plurality of modular CSC cells 10 connected in parallel with each other between the AC side and the DC side of the CSC, each modular cell comprising a plurality of switches 15. The CSC is configured for being connected in series with an HVDC transmission line 3 and for injecting a voltage in series with the HVDC transmission line at the DC side of the CSC.
