The technical and cost information of DG sets is tabulated in Table 15.4. 3. Therefore, to understand the sensitivity of the levelized cost with the fuel price escalation factor, a sensitivity analysis has been performed. The voltage is regulated by adjustment of the automatic voltage regulator for emergency diesel generators until the voltage difference between the incoming and running voltage is within the voltage error setting of 4%. We have also explored the electrification option with a DG in the village for the purpose of cost comparison. Also for power factor of 0.8 to 1.0, it is important to understand the role of automatic voltage control relay (AVR). On the other side, for PVA power superior to the load power demand, the load is supplied by PVA power and the excess energy is stored, if possible. A marine diesel generator set is shown in figure 1. The green part is the region ideal for the DG to operate; it is the window of 0.8 to 1.0 power factor. First a comparison between the demanded load power and PVA power is done, resulting in positive or negative reference power p∗. As a unit of power produced by DG costs 15-20 rupees with a typical efficiency of 30-35%, improving the efficiency of alternator will result in significant reduction in diesel consumption per unit produced. More efficient and powerful than gasoline. A marine diesel generator set is shown in figure 1. Daniel holds a Master’s degree in Arts and apart from working as a freelance writer, is a rather successful author of science fiction stories published in several literary magazines. By the plot, it can be inferred that power factor of client-2 can be improved for obtaining better performance from diesel generator. For many years, design technology of diesel generator sets has been used to achieve high power efficiency and environment-friendly operation. The most efficient generators vary depending on an individual’s or facility’s specific needs. Individual services to each diesel generator are separated but, where it is necessary to run systems in close proximity, then adequate protection is provided to each system to prevent common failure. The diesel generator is coupled to the AC–bar of the system (AC–generator). Diesel generator sets are widely used in modern industry for high energy density and dynamic stability. For a diesel generator of To compensate for extra current losses, generator will have to produce more KW at 0.8 pf than at 1.0 pf. The recommendation of diesel generators, because of its low maintenance cost and longevity. And the red area represents the load operation which will have damaging effects on the DG. DuroStar is a brand of generators that are known to be dependable and of great value. The hourly fuel consumption of DG is assessed using the following equation [86]: where Df(t) is the hourly fuel consumption of DG in L/h; PDg is the hourly DG generated power, kW; PDgr is the DG rated power, kW; and αD and βD are the coefficients of the fuel consumption curve, L/kWh; these coefficients were considered in this study to be 0.246 and 0.08145 [87]. However this induced current has a limit and thus DG cannot supply a load of power factor more than 0.97 leading. The diesel generator can supply energy to the load directly but also charge the batteries. Ambient conditions of temperature are extremely crucial for proper ignition and functioning of a generator. Now, to compare the efficiency at 0.8 and 1 power factor, consider exact same active load on the output sides of two diesel generators. Variation of LCOE with variation in the fuel cost escalation factor. A brushless, three-phase, 400 V DG with power factor of 0.8 with revolving field and directly coupled was used for the cost analysis. The largest diesel engine in the world peaks at 51.7%. 7.28 shows the system operating mode diagram of Dongfushan Island microgrid. DuroStar DS7000Q . Its power output automatically makes up for the difference between wind power and loads. The minimum and maximum allowed battery SOC were 30% and 95% of the battery capacity. Consider two DGs of 500KVA, with DG1 supplying an active load of 400KW on 0.8 power factor and DG2 supplying 400KW on 1.0 power factor. The economic and reliability differences we find between diesel and natural gas generators are relatively modest. Adding capacitors as filters under such situation will reduce the distortion of the current waveform and will improve the power factor. Power factor plot of 2 DG’s at Zenatix’s Customer side. In an office space most of the loads consists of computers or laptops which are single phase non-linear loads. Charging storage with power superior to its limit will shorten storage life; therefore at least one source needs to be limited or cut off. Accordingly, many studies on low noise and vibration have been performed. Stationary diesel engines powering electric generators that put out an alternating current, usually operate with alternating load, but fixed rotational frequency. For an independent microgrid, the operating strategy is one of the deciding elements for optimal configuration and operating parameter settings of the energy storage system and critical for operation stability. Once the diesel generator has been initialized, it will be kept on for at least one duty cycle. B. Mainali, R. Dhital, in Solar Energy Storage, 2015. Efficiency expressed as a combined efficiency of the both… 4.22. Concerning reliability, a diesel generator is able to provide power quickly and continuously during an important time period. So the power factor has to be kept between 0.8 and 1.0. The contribution of the diesel generator increases accordingly from 29 to 32%. 9.7. [3], Refer to the image below for the effect of power factor on DG’s efficiency, which is published by a leading manufacturer of diesel generator in India. For many years, design technology of diesel generator sets has been used to achieve high power efficiency and environment-friendly operation. Considering the limits such as minimum operating power and rated power of the diesel generator, the method of controlling PV power and wind turbines can be used to keep the diesel generator operating within a reasonable range. This chart approximates the fuel consumption of a diesel generator based on the size of the generator and the load at which the generator is operating at. Engines or generator sets may have more than one rating, e.g. [2] After this limit, AVR gets cut off and DG will be tripped on over-voltage. Also, the reactive power that can be supplied by it is 300KVAr. Dongfushan Island microgrid mainly has the following three operating modes: Diesel generator as the main power source. Full charge and discharge mode of the energy storage system. Distortion power factor arises due to harmonics present in the system and this cannot be compensated by adding shunt capacitors. If it is set to a relatively low value (e.g. Figure 7.28. Fuel efficient: You will get much better fuel efficiency with a diesel generator than a propane generator. In addition, the algorithm is supposed to take into account the value imposed for a final SOC equal to the initial SOC (for more clarity this calculus is not shown in the flowchart); this is done only during the iterations of the last hour of the operation duration. Fig. Indications of ‘auto synch locked out’ when a close signal has been given and ‘auto synch complete’ when the switch has closed, inform the operator of the end results. ... either with mostly partial load, or intermittently, with full load. (2.2) as follows [3]: where Ngen is number of the diesel generators, Pgen is the power generated (kW), Pn is the nominal power generated by the diesel generator (kW), and ηgen is efficiency of the diesel generator. Effect of power factor on the efficiency of diesel generator. It provides 5500 running watts and 6000 peak watts. In such conditions, level of distortion in current is very high. To reduce the vibration of rotor system, which is mainly exerted by crankshaft, theoretical prediction methods have been developed focusing on the torsional and axial vibration of a crankshaft. To reach the maximum service life of a battery, manual maintenance is required on a regular basis. The true power factor of an electrical distribution system is a multiple of two contributing factors, displacement power factor and distortion power factor. Diesel generators are very useful machines that produce electricity by burning diesel fuel.These machines use a combination of an electric generator and a diesel engine to generate electricity. When the energy storage system operates as the main power source, the diesel generator should be shut down to avoid asynchronous parallel operation, and the energy storage converter adopts V/f control to provide the voltage and frequency support for the AC bus. During normal operation, the system mainly realizes operating mode switching manually or automatically. If you are looking for the most fuel efficient generator, it is likely to be a diesel engine. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas.
