Simulation testing device for ship high-voltage electricity

Abstract

The invention discloses a simulation testing device for ship high-voltage electricity. The simulation testing device comprises a power distribution system, at least one set of high-voltage power distribution screens, an energy management controller and an adjustable load device. The power distribution system comprises two or more generator sets. Each generator set comprises a low-voltage alternating-current generator, a motor and a unit drive device. Each unit drive device comprises a unit drive controller, a transducer and an electric potentiometer. Each high-voltage power distribution screen comprises a load control screen, a generator control screen, a synchronous control screen and a connection control screen. The adjustable load device comprises a resistance load and an inductive load. The energy management controller is connected with the synchronous control screens, the connection control screens, the generator control screens and the unit drive devices through communication buses. According to the simulation testing device, the ship high-voltage power distribution screens are introduced into a laboratory, and therefore the situation that the laboratory is only provided with a low-voltage power distribution screen simulation system or a high-voltage power distribution screen simulation system in the past is changed.

Description

technical field [0001] The invention relates to a simulation technology of high-voltage power for ships, more specifically, a simulation test device for high-voltage power for ships. Background technique [0002] With the continuous improvement of the electrification level of ships, the number of electrical equipment on board is increasing, and the power load is rising rapidly, which makes the power of the generator gradually increase. For the traditional ship low-voltage power system (below 500V), the system current gradually increases. Cables The cross-sectional area gradually increases, and it is technically difficult and economically unreasonable to manufacture low-voltage high-power motors. For this reason, increasing the voltage level of the power system has become a problem that must be considered in the development of power stations in the direction of large capacity. This is also the cause of the high-voltage power system of ships, and has become the development tre...

Problems solved by technology

[0003] At present, the research on marine high-voltage power system products in my country is still in its infancy. Most of the crew, students and related researchers in China still don't know enough about the high-voltage system of ships. Establishing a complete performance testing platform will help advanced The application research of control theory and control technology in ship high-voltage power system can also be used as a teaching platform to provide practical guarantee for training high-ability and high-quality students
