Portek International is showcasing their Kam Hybrid System, which uses variable engine speed and energy storage to reduce fuel consumption and emissions in rubber-tired gantry cranes (RTGCs). The system was retrofitted to an existing RTGC in China in 2008 and achieved a 79% reduction in idling fuel use and up to 47% reduction during operation. It can be installed on new or existing RTGCs without interfacing with crane controls. The presentation provides details on the system components, test results, project timelines, and estimates fuel savings of 45-60% depending on the energy storage device used.
The document presents a sensorless vector control method for 3-phase induction motors using sliding mode field oriented control. It includes rotor speed estimation from stator voltage and current measurements, which is then used as feedback in field oriented control without shaft sensors. The paper proposes a new sensorless vector control approach combining speed estimation to overcome the need for speed sensors, with a variable structure control law using an integral sliding surface to compensate for uncertainties in the system.

The document discusses using ultracapacitor systems and energy storage to improve the efficiency of cranes. It describes how capturing regenerative braking energy with ultracapacitors and a converter can reduce a crane's primary energy usage by 5-10% and lower fuel consumption and emissions. Adding a larger ultracapacitor module and optimizing the control strategy based on a cost function could achieve energy reductions of 27-31%, fuel reductions of 13-16%, and eliminate soot emissions altogether. This hybrid approach provides flexibility and simplicity while using proven technology to provide economic and environmental benefits over conventional cranes.
Kollmorgen benefits of direct drive technologyElectromate
Direct drive technology provides three main benefits over traditional mechanical transmission systems: 1) It eliminates compliance between the motor and load, allowing for precise motion control; 2) It is not affected by inertia mismatches between the motor and load; and 3) It has been successfully used in applications with up to 1000:1 inertia mismatches, compared to 10:1 for standard servo systems. Direct drive uses the motor to directly couple and move the load without any gearboxes, belts, or other mechanical interfaces.
This document summarizes a presentation on improving energy efficiency in foundries. It discusses the South African foundry industry and provides definitions related to energy efficiency. It then examines opportunities for energy savings across various foundry processes like melting, holding, tapping, and maintenance. These include using batch melting, avoiding holding metal, preheating scrap, improving refractory maintenance, and more. The conclusion is that continuous small improvements can achieve energy savings and there are retrofitting options available for many furnaces.
This document summarizes a presentation on improving energy efficiency in foundries. It discusses the South African foundry industry and provides definitions related to energy efficiency. It then analyzes where foundries use the most energy, such as in melting, and provides opportunities to improve efficiency in each stage, such as optimizing scrap selection and charging practices, improving furnace technology, and maintaining equipment. The conclusion emphasizes that continuous, small improvements can achieve energy savings rather than any single technological solution.
This document provides an overview of the Advanced Boiling Water Reactor (ABWR) including key reactor specifications and design features.

The document describes the reactor pressure vessel, core internals, and standard fuel designs that can be used. It highlights improved safety features of the ABWR compared to previous boiling water reactor designs.

This document discusses off-grid solar power as the lowest hanging fruit for implementing solar power in the MENA region. It summarizes that there are several gigawatts of existing micro-grids that run on diesel fuel. While solar is becoming more cost competitive with diesel, high upfront costs, load management challenges, and the temporary nature of off-grid needs have prevented solar from taking over more of the off-grid market. However, solar-hybrid systems are now competitive in many areas and can overcome challenges through innovations like containerized solar generator units and turbogenerator systems.

Ro-Pax, i.e. roll on/roll off passenger vessels, typically sail short distances from island to island in an archipelago. The operating profiles for the vessels are constantly changing, which sets challenges for energy efficiency and fuel consumption. C&A Electric and Vacon Korea have designed an efficient energy production solution to improve shaft generator usability. This is used on two Ro-Pax vessels built for the Attica Group1, the parent company of Blue Star Ferries.
1) Ancillary services are necessary to support power grid operations and maintain power quality, reliability and security. They include frequency support, reactive power support, and black start capabilities.
2) India's power grids currently face issues like frequent unplanned load shedding due to lack of flexibility and reserves. There is a need for ancillary services to harness available generation and relieve congestion.
3) The document proposes a framework for Frequency Support Ancillary Services (FSAS) in India utilizing fragmented generation capacity through competitive bidding on power exchanges. This aims to stabilize grid frequency and reduce load shedding.
The document provides an overview of static excitation systems for synchronous generators:
1. Static excitation systems provide direct current to the rotor of a synchronous generator to regulate the stator voltage, reactive power, or power factor with fast dynamic response.
2. The main components are an excitation transformer and a thyristor power converter cubicle that controls the excitation current supplied to the rotor.
3. Compared to brushless excitation systems, static excitation systems have advantages of reliability, fast field de-excitation, complete redundancy, improved dynamic response, and simplified maintenance.

Electric Vehicle Regenerative Acceleration Innovation ReportThane Heins
The document evaluates regenerative acceleration generator technology. It describes how regenerative braking systems in electric vehicles work by converting kinetic energy into electrical energy. However, regenerative acceleration is more difficult to understand as it appears to break laws of physics. The evaluation observes demonstrations of a technology called Regenerative Acceleration Coils that claims to accelerate rotational motion using regenerative principles. It aims to test the claims and arguments to either validate the technology or identify weaknesses through further analysis and testing.
This presentation discusses how smart grids may perform during crisis situations like severe storms. It questions whether smart grid planning fully considers crisis management. Control rooms may struggle with increased data from smart grids during emergencies. Case studies on self-healing networks show benefits but also risks to consider. Customers may not be ready for potential smart grid reliability issues in crises. The presentation recommends a gradual, phased approach to smart grid deployment that first focuses on reliability.
This document describes a control methodology for a photovoltaic (PV) system interfaced with a distribution network. It proposes a control strategy based on an inner current control loop and an outer DC-link voltage regulator. A modal analysis is also conducted to characterize the dynamic properties of the system and evaluate the robustness and interactions between the PV system and the network/loads. The results confirm that under the proposed control strategy, the dynamics of the PV system are decoupled from those of the distribution network, and therefore the PV system does not destabilize it.
