摘 要：
A system for extracting and converting into complex power the electrical energy conveyed through a high voltage direct current (HVDC) transmission line, the system being serially mounted along that transmission line. The system comprises converter bridges to convert the
transmission line high voltage into AC active power and a unit, connected to the line, for generating reactive power and feeding the latter through both the
converter bridges and the load mounted across the system output. Moreover, there is provided a device for controlling the rate of extraction and conversion of the HVDC energy in function of the active power supplied by the generating unit. This control device ensures that the load requirements in active power are entirely supplied by the converter bridges alone. A voltage regulator is associated to the generating unit for the purpose of keeping constant the output voltages of that generating unit, thereby causing a nul output active power from the unit, in steady state. The tapping system is
generally under a voltage proportional to the energy extracted on the transmission
