Ship power supply remote test system and method

Abstract

The invention provides a ship power supply remote test system. The ship power supply remote test system comprises a plurality of test units; each test unit comprises a test power supply used for generating alternating current with rated voltage and rated frequency; a load unit which comprises a plurality of resistance load units, a plurality of reactance load units, a plurality of contactors and resistance load units, wherein the reactance load units have set resistance values and reactance values, one contactor corresponds to one resistance load unit or one reactance load unit, and the resistance load units and the reactance load units are connected in parallel with the test power supply through the corresponding contactors; and a control unit which is in signal connection with the contactor, and drives the contactor to open / close according to an externally input power factor, a test power value and a power fine adjustment instruction so that the actual power value of the load unit isadjusted to reach the preset precision. The invention also provides a ship power supply remote test method. According to the system and the method, the efficiency and the precision of ship power supply testing can be improved.

Description

technical field [0001] The invention relates to the field of ship power supply, in particular to a remote testing system and method for ship power supply. Background technique [0002] In order to ensure the safe navigation of the ship, it is necessary to conduct a test before the official use of the ship's power supply, that is, to test whether it can work effectively under the set power for the set period of time. For example, test whether the ship power supply can work stably for 100 hours under the active power of 15KW. Or it is also necessary to measure whether the set working time can be achieved under the set active power and reactive power at the same time according to the power factor. [0003] As more and more types of power sources are equipped on ships, the ship power test system also needs to be constantly updated. Through the diversified design of the ship power supply test system, it can meet the test requirements of different types of ship power supply. Am...

Problems solved by technology

However, during the ship power supply test, due to the long distance between the test power supply and the load, the long-distance lead wires will cause the voltage drop of the test power supply and affect the test accuracy.

At the same time, the heat generation of the load itself (affected by the load arrangement and load performance) will also affect the accuracy of the power supply test
