Intelligent high-voltage power supply control system on dock

Abstract

The invention discloses an intelligent high-voltage power supply control system on a dock. The system is provided with a three-level structure, i.e. an embedded main processor, a co-processor and an interface module, to calculate pulse data, generate and send pulse, and monitor the state of each level of power module group, wherein the main processor calculates the duty cycle in a period according to the voltage phase and the direct-current voltage of the current switching period according to needs; the co-processor performs phase shift and synchronous processing on the data of the duty cycle according to the cascade level of a power module to generate a pulse sequence containing a time-sequence relation; the interface module is mainly used for performing dead-time compensation and narrow-pulse elimination on the pulse sequence sent by the superior co-processor, packing the pulse sequence according to a communication protocol and sending the pulse sequence to an optical fiber interface, and the pulse sequence is transmitted to each level of power module group through the optical fiber interface; the interface module receives the state data transmitted by each level of power module group at the same time, and after being parsed, the data is read by the main processor.

Description

technical field [0001] The invention relates to the technical field of high-voltage power supply control for ship power supply, in particular to an intelligent high-voltage power supply control system for a wharf. Background technique [0002] In recent years, my country's shipbuilding industry has developed rapidly, and now my country has become a major shipbuilding country in the world. More and more countries and regions are ordering and repairing various ships in our country's shipyards that meet their standards, frequency and voltage requirements. During ship repair and construction, a large number of equipment on board need 60Hz power supply for normal use. Since the power frequency standard of my country's grid power supply is 50Hz, before the ship's generator is put into normal use, these equipment that need 60Hz power supply must have a power supply that matches its electrical system. Therefore, a high-quality stable frequency and voltage stabilized power supply h...

Problems solved by technology

The entire main circuit system contains multi-level power circuits and the control pulses of each level of power circuits must abide by strict timing. Therefore, it is difficult to complete pulse distribution only by sequential execution devices such as DSP. This type of power system usually has the main algorithm function , needs to interact with many external interfaces (including analog sampling and output ports, IO ports, communication ports, etc.), so it is difficult to complete a single CPU system; so far there is no reference design standard for the control system required by this type of power supply, so it is necessary to provide This type of wharf intelligent high-voltage power supply design dedicated control system
