Automotive muffler is a component used to reduce the noise of high pressure exhaust gases that are produced from the internal combustion engine. The main objective of this study is to analyse the effect of the muffler parameter to the sound pressure level (SPL) at the tail pipe noise using GT-Power simulation software. The muffler runs with a Proton Iriz engine model at engine speed from 1000 RPM to 6000 RPM at full load condition. The parameter of each muffler model was compared to determine the most suitable model to reduce the noise at tail pipe with lower backpressure difference. The results obtained was compared with those from previous research as a means of benchmarking. The muffler model should not produce a backpressure difference of more than 5% from the benchmark systems. It is found that the most suitable model in reducing the tail pipe noises is Model B, which manage to reduce the noise by 3.07% (average) of the sound pressure level with backpressure difference of 0.35% only by only reducing the perforates number and shorten the perforates length.

Turbine Model

The power system simulation software usually use ideal hydraulic turbine model in transient stability simulation. Ideal model is the linearization of turbine steady state equation, it can hardly adapt to the various operation conditions in power system. In this paper, a modified nonlinear model of hydraulic turbine is proposed based on basic hydraulic turbine equations, the model can better reflect the dynamic behavior of the turbine since transient component are taken into account. Field test data verify the validity of the proposed model. The model can greatly improve the accuracy. Furthermore, the model is very simple so that it can be easily used in power simulation software

Performance And Emissions

The scarcity of oil resources and the rise of crude oil price had driven the whole world to seek for an alternative fuel for automotive industry. One of the prospective alternative fuels for compression ignition (C.I.) engine is compressed natural gas (CNG). In order to operate CNG in a C.I. engine as mono-gas engine (RE), several modifications are required. The modifications that involves are compression ratio, fuel injection type, addition of spark plug and fuel itself. So as to reduce the time in preparing the experimental test bed and high cost analytical study a 1-dimensional simulation software GT-Power was introduce. The GT-Power simulation model for a 4 cylinder medium duty C.I. engine (DE) and RE has been built to study the effects of conversion process to the performance and emissions of the engine at various operational conditions: low, medium and high load conditions. As compared with DE model, results from RE model showed loss in brake power (BP) and brake thermal efficiency (BTE) by 37.3% and 19% respectively. Meanwhile, for brake specific air consumption (BSAC) RE predicted to undergo an average of 19412.6 g/kW-h and increment in volumetric efficiency by percentage of difference 22%. In other side, oxides of nitrogen (NOx) RE engine model predicted reduction of 48.1% (engine mode 1-9) and increased in hydrocarbons (HC) by 90.3.

Traction Power

In 2012, KTMB launched a new fleet of China-made 6-car electric multiple units (EMUs) to augment their existing 3-car EMUs, the objective being to expand the capacity of its Klang Valley train commuter service from 33,000 to 95,000 passengers during the morning and afternoon peak hours. Due to significant expansion in train traffic density, it was essential to investigate whether the existing 25kV overhead centenary system (OCS) electrical network infrastructure could support the ensuing electrical power demands/loads due to the additional tractive effort of the 6-car trains and increased train traffic density. Traction power simulation study using MM-TRAIN software was conducted for this purpose. This paper illustrates the indispensable tool of traction power simulation software to access the performance of moving rail traction loads under normal (no outage) and under first emergency feeding conditions (n-1 outage contingency)

Smart grid is the development trend of the power industry under the new situation. As an important part of smart grid, smart power consumption directly faces the society and power users, and plays a very important role in the construction of smart grid. With the development of intelligent power construction, the traditional power service can not meet the needs of users to participate in demand side management and interact with the power grid in time. Therefore, the construction of a new intelligent sensing power measurement system to improve the quality and level of intelligent power service has become the focus of current power industry research. Firstly, according to the requirements analysis and design principles of the intelligent sensing power detection system, this paper proposes the function analysis and three-tier architecture design of the intelligent sensing power detection system. The intelligent sensing power detection system is logically divided into business application layer, network communication layer and sensing device layer. Externally, it realizes data integration and interaction with power consumption information collection system, marketing business management system and other intelligent power consumption information systems. Internally, it realizes interconnection with user side perception interactive terminal and perception unit, and realizes data acquisition, information transmission and control functions of power consumption terminal equipment. This paper presents a method of applying intelligent sensing technology to data editing environment of power simulation software, and realizes online error detection of simulation original data, automatic completion of keywords, automatic prompt of data card and intelligent help of data domain. The power simulation data editing software with intelligent sensing function developed in this paper is suitable for primary and advanced users, which can improve work efficiency and reduce error rate. The configurable rule management method applied in the implementation of intelligent sensing technology extends the application of data editor to the developers of models and algorithms, and provides a simple way for the timely upgrade and release of new models and algorithms.
