| With the continuous development of shipping industry and the modernshipbuilding technology, the complexity of the ship power system is increasing andthe requirement of reliability of ship power system and energy-saving is higher andhigher. Therefore, the research on ship power system technology is of vitalsignificance for improving the economy and reliability of the ship. The key point ofpresent study is to build a multimode ship power station plant test-bed, which canautomatically control ship power station and monitor power quality of power station.In order to improve the safety and the economy of ship power station, optimizationcontrol technology can be investigated on this test platform. The main content ofpresent study has the following parts:1. The relevant literature were reviewed and relevant technical materials wereanalyzed. In addition, the corresponding research oritation, sitution and significancewere expounded.2. According to the operation characteristics of power generation equipmentunits and the corresponding control strategy, appropriate mechanical and electricalequipments were chosen to simulate the corresponding power units. Electric motorsdriven by the inverter were used to drive the generator to simulate the turbineauxiliary diesel. Moreover, Siemens S120was used to simulate the shaft generatorand its exhausting gas turbo generator. According to the characteristics of eachoperation unit of shaft generator and its gas turbine generator, inversioninterconnection technology was applied to it, while direct interconnection mode wasused to auxiliary diesel generator. Then all units can linking by integrating all thegenerating units.3. The formation of ship multimodel plants was reviewed in this paper. Toincrease running reliability and energy efficiency of the ship power station, thedesign of the model of ship power station was analyzed. Multimode ship powerstation consists of diesel generating sets, thrusting shaft generator set and the hostgas turbine generator set. According to the corresponding operation characteristics,reasonable capacity and operation mode were chosen, it consisted of auxiliary diesel generating model, inverter parallel system model, and select the appropriate controlstrategy.4. Power quality detection and corresponding standards were introduced, andvirtual instrument technology was used to realize real-time acquisition and analysisof power quality. NI data acquisition card and the Lab VIEW platform software wereused to analyze real-time power quality of the test bench.5. the principle diagram and the design of hardware and software of the test-bedwere introduced. It mainly includes the test bench for electrical schematic diagram,power station control system and the software design of PC monitoring system. |
