Virtual Dpu Power Plant Simulator

Along with quick development of the computer technology and information technology, the simulation technology get a substantial development. That the extensive application of the Distributed Control System (DCS) in the power station control also put forward a new topic about the simulation technology of station control system in the meantime. And adopting a virtual DPU method is a latest development of DCS simulation technical in the recent years. The virtual DPU technique means on board imitate DPU system to constitute to imitate a true technique and the software of the movement of the DPU procedure in the PC. Adopt the virtual DPU technique carries on DCS to imitate to really have very high software to imitate a true degree with the lower cost, and can used for the training that the heat controls a personnel.The method to carry out the virtual DPU technique (VDPU ) which based on NETWORK 6000 System is to develope VDPU technique in the PC environment which adopting the general software development platform, to carry on scanning performance about the download document of true DCS set through an intelligence translation conversion software. Forming the virtual DCS parameter database to meet the request of simulation technology and the analysis calculation procedure. We imitated several work processes of DPUs in one set PC machine, thus we made the virtual DCS reappear the DCS function of NETWORK 6000 system.In order to carry out the communication between the model of simulation machine and the virtual DPU (VDPU )technique, and to complete the status control of the virtual DPU. This procedure include:the running and freezing of the virtual DPU, saving and reading the work condition in order to carry on a valid management to the VDPU, we also complete the function of on-line start and stop, the function of on-line download, ascend to carry and on-line modification and conservation of controling strategy.We developed the replay function of actual accident in the simulation system which is based on the virtual DPU technique , recording actual data of the DCS system to build up a conjunction with virtual DPU, to display the process of the actual accident status completely in the simulation machinehe, which contributing to trouble analysis.The simulation machinehe of 135 MW generator set of the the HANGZHOU HUADIAN BANSHAN power generation CO., LTD which developed with the virtual DPU technique (VDPU ) had already acquired a good application.
