Embodiment Construction

[0050] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051]The diesel generator set load test system of the present invention is aimed at the problems of energy consumption, large floor area, low reliability and serious pollution to the power grid in the diesel generator set test device in the prior art, and proposes that the diesel generator set should be discharged when the diesel generator set is tested. The alternating current with changing frequency and amplitude emitted by the unit is isolated by the input isolation transformer device, rectified by the PWM rectifier device and turned into direct current, and then passed through the DC chopper device and PWM inverter device in turn, and then converted into three-phase power by the PWM inverter device...

Abstract

The invention discloses a system for the load test of a diesel generating set, which is used for supplying power for the load in load test of the diesel generating set so as to reduce the energy consumption. The system comprises an input isolating potential device, a PWM (Pulse Width Modulation) rectifying device, a direct current chopped wave device, a PWM inverter, a filtering device and an output isolating potential device which are connected in sequence; the input isolating potential device is used for isolating the diesel generating set from the PWM rectifying device; the PWM rectifying device is used for converting the alternating current voltage output by the diesel generating set into direct current voltage; the direct current chopped wave device is used for carrying out direct current protection on the direct current voltage; the PWM inverter is used for converting the direct current voltage into three-phase alternating current voltage; the filtering device is used for reducing the harmonic content in the three-phase alternating current voltage; and the output isolating potential device is used for isolating the PWM inverter from a load and supplying the three-phase alternating current voltage to the load for use. The invention further discloses a method for the load test of the diesel generating set.

Description

technical field [0001] The invention relates to the technical field of diesel generator sets, in particular to a load test system and method for diesel generator sets. Background technique [0002] Diesel generator sets are used more and more on ships, and besides being used as conventional sets for providing ship power, they are also more and more widely used for electric propulsion. Due to its unique advantages, the use of full or semi-electric propulsion has become a development trend for ships over thousands of tons, especially military ship propulsion systems. For diesel generator sets, before they are applied to specific ships, they need to be tested for their performance through various tests. [0003] In the prior art, there are various test methods such as energy consumption type test device, generator set grid connection test device and generator set grid connection test device to detect the performance of diesel generator set. The energy consumption type test de...
