Method for electromagnetic ultrahigh-voltage DC remote power transmission and distribution of ocean controllable source

Abstract

The invention discloses a method for electromagnetic ultrahigh-voltage DC remote power transmission and distribution of an ocean controllable source. A power generator provides electric energy for thewhole method and is then is connected with a deck power-end large-power rectification device and an inversion device to provide an intermediate-frequency alternating current with an adjustable voltage, the voltage is converted to a ultrahigh-voltage direct current by a deck power-end boost transformer and the deck power-end rectification device, the electric energy loss is reduced to the minimumby a long-distance ultrahigh-voltage DC power transmission and distribution ocean cable and then the electric energy is converted to an ultrahigh-voltage alternating current to be transmitted to a reactor and an underwater transformation device by an underwater power-end large-power inversion device, the electric energy is converted to a low-voltage alternating current by an underwater transformation device and then is supplied to an underwater emitter rectification inversion unit for use. By the method, the electric energy loss of traditional long-distance AC power transmission is greatly reduced, the power and the efficiency of long-distance electric energy transmission are improved, the electric energy demand of an ocean controllable source electromagnetic emitter at the bottom of sea is effectively guaranteed, and meanwhile, the problem of three-phase unbalance is thoroughly solved.

Description

technical field [0001] The invention relates to the field of geophysical prospecting, in particular to a method for providing ultra-high-power electric power guarantee for a transmitter near the seabed, aiming to ensure that the electromagnetic transmitter can have sufficient power sources to ensure the smooth operation of the entire system when it is working. Background technique [0002] In the 1880s, Edison established the world's first direct current transmission system, but due to the lack of direct current transformation technology, direct current transmission has great limitations. In the 1990s, the advantage of high-voltage transmission of alternating current appeared, which greatly reduced the energy loss on the line. It was not until the 1950s, with the gradual maturity of the commutation technology, that HVDC power transmission re-entered the field of vision of mankind. In the 21st century, with the rapid development of power electronics technology, flexible dire...
