The average differences for the power outputs and thermal efficiencies of the gas turbine, steam cycle, and CCGT plant are less than 2.0%, 1.5%, and 0.6%, respectively. The results show the predictions of the two models ( Aspen Hysys and GateCycle) agree well. To evaluate the model’s performance, its predictions are compared with those of an equivalent model from GateCycle. The modeling strategy and solution procedure can be extended to simulate the off-design operation of any CCGT plants and are generically applicable to other process simulators (e.g. compressor, combustor, turbine, heat recovery steam generator, and steam turbines) are implemented in Aspen Hysys, and a specially tailored procedure is proposed for solving them.
The modeling equations that rigorously capture the full off-design characteristics of various plant components (i.e.
This paper aims to present a methodology for simulating the off-design operation of a triple-pressure reheat CCGT plant in Aspen Hysys.
Enhancing their thermal performance is essential for mitigating carbon emissions. Third, its model can be made dynamic for predicting the real-time behaviour of a CCGT plant.Ībstract Combined cycle gas turbine (CCGT) power plants are becoming increasingly important for electricity generation. Second, it allows easy integration with various energy systems such as CO2 capture, organic Rankine cycles, fuel cells, LNG terminals, air separation, absorption chillers, etc. First, its use of the well-proven real-gas Peng-Robinson fluid package may give more accurate predictions. On the other hand, Aspen Hysys may have some advantages over GateCycle. The minor discrepancies are primarily from the differences in gas enthalpy correlations. The average relative deviations for the power outputs and thermal efficiencies of the gas turbine, steam cycle, and CCGT plant are less than 2.0%. A comparison with an equivalent GateCycle model shows that the predictions of the two models ( Aspen Hysys and GateCycle) are comparable. To our knowledge, this is the first such model in the literature. Full list of changes.Abstract A detailed model is developed in Aspen Hysys for simulating the operation of a triple-pressure reheat combined cycle gas turbine (CCGT) power plant.
Settings to add or override color info have been added to MKV and WebM muxers. A subset of color info relevant for HDR support is retained in copy mode when both input and output video are stored in Matroska / WebM containers.
A dedicated MOV muxer is now available, replacing silent fallback to MOV muxing mode within the MP4 muxer.
You don’t necessarily have to learn how to use a complex software in order to get professional results. The developers of this application have managed to ensure proper initialization of Qz for jpeg export, fixed importing MP2 audio detected as MP3, fixed deleting chunks of the video leading to seek errors, better detection of double PFS input files, better TS/Demux initialization (avoiding dropping audio), fixed issue when source has more than 4 tracks, fixed management of PCM audio and many others.ĪviDemux is the proof that you can encode and edit video files even if you are not an expert and that a simple piece of software can attract stellar user reviews and be reliable as well. The latest versions of AviDemux come with advanced features aimed at the various types of operations you may perform, regarding image export, audio, editor, TS/Demux, MP4/Demux and subtitle capabilities. The application also offers support for audio formats like MP3, WAV and OGG. This virtual item is similar to VirtualDub, but the difference is that you can encode VCD/SVCD/DVD mpg too.ĪviDemux supports the most common codecs (M-JPEG, MPEG, DivX, Xvid, huffyuv, WMA and so on) since it is fitted with libavcodec and libmpeg2. Subsequently, you can edit, cut, append and filter videos and re-encode them to AVI or to MPEG 1/2. In a basic window you will be introduced to various processing tools, decoder options, filters and frame rate configurations.
Use it for MPEG, AVI, DivX, VCD, SVCD and DVD MPG and you won’t need other complex software.ĪviDemux's GUI is dedicated to the average user and it has an intuitive, user-friendly interface. A small tool, AviDemux will do its job fast and it is perfect for adjusting home-made videos.
