Abstract The main sources of air pollution in ports are ships, on which electrical energy is produced in the autonomous generating sets Diesel-Generator. The most effective way to reduce harmful exhaust emissions from ships is to exclude marine generating sets and provide the shore-side electricity in “Shore to Ship” system. The main problem in the implementation of power supply for ships from land is connected with matching parameters of voltage in onshore network with marine network. Currently, the recommended solution is to supply ships from the onshore electricity network with the use of power electronic converters. This article presents an analysis of the „Shore to Ship” system with the use of generating sets with LNG gas engines. It shows topologies with LNG - Generator sets, environmental benefits of such a solution, advantages and disadvantages.

In this book, we discuss reliability in electrical energy converters. The first step is introducing these devices and recognizing their main functions as well as their importance. Electrical energy conversion systems consist of two main parts: Electrical machines and Power electronic converters. Electrical machines are used for converting electrical energy to mechanical one in the generator state and vice-versa in the motor state. To emphasize the importance of these devices, it may be noted that electrical motors consume about half of the total generated electrical energy in the world. On the other hand, power electronic converters are essential equipments which are used for electrical energy conditioning. These equipments have observed considerable growth in modern industries in recent years. Because energy conditioning allows us to use energy with higher efficiency and better performance, in this chapter, importance of electric power converters in modern industries is presented. The aim of this presentation is showing the dependence of various industrial functions to conversion of electric power. Basic relations of various electrical machines as well as power electronic converters are presented. In each section, some typical industrial examples are presented. This background will be used in the next chapters for reliability calculation and improvement. In fact, this chapter is an introduction on reasons of writing an individual book about reliability of electric power converters.

Air Pollution Emissions

Abstract The decisive source of air pollution emissions in ports is the berthed ships. This is primarily caused by the work of ship’s autonomous generator sets. One way of reducing the air pollution emissions in ports is the supply of ships from electricity inland system. The main problem connected with the power connection of ships to the inland network is caused by different values of levels and frequencies of voltages in these networks (in various countries) in relation to different values of levels and frequencies of voltages present in the ship’s network. It is also important that the source power can range from a few hundred kW up to several MW. In order to realize a universal „Shore to Ship” system that allows the connection of ships to the electricity inland network, the international standardization is necessary. This article presents the current recommendations, standards and regulations for the design of „Shore to Ship” systems.

Supply Mode

The power supply mode of island microgrid with a variety of complementary energy resources is one of the most effective ways to solve the problem of future island power supply. Based on the characteristics of seawater desalination system and water demand of island residents, a power allocation strategy for seawater desalination load, storage batteries, and diesel generators is proposed with the overall consideration of the economic and environmental benefits of system operation. Furthermore, a multiobjective optimal operation model for the island microgrid with wind/photovoltaic/diesel/storage and seawater desalination load is also proposed. It first establishes the objective functions which include the life loss of storage batteries and the fuel cost of diesel generators. Finally, the model is solved by the nondominated sorting genetic algorithm (NSGA-II). The island microgrid in a certain district is taken as an example to verify the effectiveness of the proposed optimal method. The results provide the theoretical and technical basis for the optimal operation of island microgrid.

Electrical energy is a primary need in modern human life. However, with the increase in fuel prices, the right technology is needed to overcome it, in the form of battery and inverter innovations which are combined to produce an output of 220 volts ac which has the same capacity as PLN electricity. This PkM DPRM activity was held in Manggar Village for 3 days, namely @ u on July 30, August 3 and August 4, 2020 which was attended by fishermen, fried food traders and Manggar Village employees themselves. The equipment is designed with a capacity of 300 watts and 1000 watts, tailored to the needs of the residents. The benefit greatly eases the use of diesel generator sets for fishermen, which from Rp. 108,000 / month, has now become Rp. 0, -. Likewise for fried food traders, who originally paid Rp. 70,000 / month for electricity for lighting at night, now it is Rp. 0, -. Based on the results of the questionnaire, participants are very grateful for the presence of this technology in their village. At least the motivation for other residents to implement these tools in everyday life. Keywords: power plants without fuel, save energy, fuel, lighting, manggar kelurahan

For electrification of decentralized energy consumption facilities, as a rule, constructed an autonomous diesel power station, the operation of which involves the use of diesel fuel mainly to start the unit, and the rest of the time the diesel generator sets operate on treated oil. To reduce fuel consumption (treated oil) and reduce the load on diesel generators, it is proposed to use as the main power source for oil pumping stations, located in regions with high wind energy potential – an autonomous hybrid power-supply system – wind-diesel power station with a parallel operation of the wind and diesel power station. The article provides an operation scheme of a wind-diesel power station. In case when there is no possibility to place diesel generator sets of the equivalentcapacity in the powerhouse hall, then the article describes the optimal calculation algorithm for power distribution between diesel generator sets with different capacity, based on solving simultaneous equations by using the Lagrange multiplier method. The article also provides a practical example of the algorithm.

Renaissance University, Agbani has a research institute with internet facility that accommodates 200 computers for student training, research and browsing. This facility becomes impossible to run due to the inability of the public utility to provide steady, reliable and efficient power. A 250KVA generating set was denoted by the school Administration and latter installed for this facility. After the installation, the facility cut off from public utility and depends wholly on Diesel generator. From experience with the performance of the existing generating sets as regards emissions and operating costs due to high cost of maintenance and diesel, a hybrid system (Diesel-Solar PV) was proposed. This paper investigates and analyzes the economic and environmental benefits of the proposed project to existing diesel generator. From the analyses, the proposed system (solar PV-diesel) has less total net present cost and less emission as a result of less fuel consumption and higher efficiency operation of the diesel genset when compared to the existing system (diesel only).
