New System

In the era of digital devices, many industries still use traditional methods of pen and paper to maintain records. One such industry is the diesel generator industry where these generators are operated without any proper supervision. The current management of these generator vans is highly unorganized. This causes a lot of miscommunication between the owners and the customers. The idea focuses on monitoring the different parameters of a diesel generator using internet-connected sensors. Parameters such as fuel consumption, AC power ON time, RPM of the turbine, and temperature are measured in real time. The system helps the owners to monitor their generators vans through one mobile application rather than depending on the on-site operators. Both the owners and customers can see how much power was consumed and how their bill was generated. Rather than using pen and paper to maintain records in the current method, the new system completely transforms the old methods into a highly digitalized modern business.

This study evaluated brake specific fuel consumption and regulated emissions from palm biodiesel fuel (palm BDF) used on diesel generators. The tests were performed at an idle and high load with different mixing rate blends between diesel fuel and palm BDF (0 %, 5 %, 10 %, 15 %, 20 %, 50 %, 100 % which was called B0, B5, B10, B15, B20, B50 and B100) respectively. The results showed at each loading mode, brake specific fuel consumption increased when the volume of palm BDF rose in the blends. At the idle mode, brake specific fuel consumption increased 1.32 %, 1.8 %, 2.8 %, 3.74 %, 5.61 %, 6.54 % for B5, B10, B15, B20, B50, B100, compared with B0. Similarly at the high load mode, brake specific fuel consumption improved 1.51 %, 1.86 %, 2.18 %, 4.78 %, 5.36 %, 6.76 % for B5, B10, B15, B20, B50, B100, compared with B0. In both two load modes, when the volume of palm BDF in the fuel blends grew gradually, the concentration of CO, SO2 and CxHy emission reduced while the concentration of NO and NO2, CO2 went up. Emission factors of CO, SO2 and CO2 at high load are higher than those at an idle load, regardless the ratio of palm BDF to diesel fue. Conversely, emission factors of NO, NO2 at high load are higher.

Power Split

The interest of this work is to develop a control strategy to most effectively manage the power split between the energy storage system (ESS) and the diesel generator of a hybrid locomotive. The overall goal is to minimize fuel consumption of the diesel engine, while maximizing battery life of the onboard ESS. This problem proves to be complex due to the conflicting cost functions of fuel economy and battery state-of-health (SOH)[1]. In other words, during a typical drive cycle, fuel consumption is minimized by placing high loads upon the battery while minimizing negative effects on SOH requires more specific loading characteristics of the ESS for the same drive cycle. This work highlights the development of several power split control strategies for effective power management of a hybrid locomotive. The progression from a strict rule-based (RB) control strategy to an equivalent consumption minimization strategy (ECMS) is realized through simulation. Likewise, the advantage of Model Predictive Control (FLC) is also shown in simulation.

Diesel Generators

Diesel generator based auxiliary power units (DG-APU) are widely used in different civil and military applications. Fuel economy and service life are probably the most important issues concerning their operation. Controlling engine throttle position in accordance with the load power allows regulating fuel supply to the engine to optimize fuel consumption. Despite the advantage of the method, control stability is sacrificed in case of light load operation as follows. When the DG-APU is running with a light load, engine throttle position should be nearly closed in order to minimize fuel consumption. If a load step is applied in such situation, engine velocity may drop sharply until complete stop because of insufficient control system bandwidth. This is why velocity and throttle position of a DG-APU should not be decreased below some level even if load power is low to maintain reliability at the expense of increased specific fuel consumption. Moreover, for small diesel-generators the throttle position is usually fixed. Thereby, relatively wide range load power variations (typical for many of diesel-generator applications) cause excessive fuel consumption. The situation may be sufficiently improved by connecting ultracapacitors (UC) on the DG-APU output terminals, introducing additional inertia allowing smoothing engine velocity decrease during a sudden load increase thus providing more time to the control system to regulate throttle position. As a result, DG-APU would be operated much more efficiently at light loads without sacrificing stability. Moreover, the UC may be used at as starter motor power source, removing starting stress from electrochemical batteries. Present work investigates the improvements in UC-supported DG-APU fuel efficiency and stability compared to conventional technical solutions. The research is based on mathematical modeling of the entire system, verified by experiments. The results support the presented ideas and quantitatively demonstrate the improved fuel economy and reliability of small DG-APUs.

Space Cooling

A vapor compression cycle (VCC) powered by the diesel generator is typically used in space cooling for the shipboard application. This system consumes large amounts of electricity. In an effort to reduce fuel consumption for cooling, two solar powered hybrid cooling system options are proposed. The first one is to use VCC with solar photovoltaic (PV) panels and the second one is to use absorption cycle (ABC) with evacuated thermal collectors (ETC). Control strategies have been set up for all three scenarios to provide space cooling for guest rooms on a cruise ship. In addition, for the PV powered VCC case, the optimum battery storage system size was investigated. It was found that the optimized PV system could reduce yearly fuel consumption and life time greenhouse gas (GHG) emission by 98% and 93%, respectively. The ETC powered ABC system would reduce the fuel consumption and GHG emission by 78% and 75%, respectively. The cost analysis indicates that the ETC system has lowest life time cost, which is 28% of the baseline scenario and 23% of the PV system.
