Generator Design

The article presents the results of studies aimed at improving the power performance indicators of linear electric generators for wave power plants by reducing the flux leakages using high-temperature superconducting (HTS) inserts placed in between the teeth. The generator design involving application of the Vernier principle for magnetic flux modulation with a translator in the form of a hollow cylinder is considered. Generators of this type are used in float wave power plants driven directly by a reciprocating float, which transmits large forces at a low motion speed. The calculations were carried out using the HTS properties modeling procedure based on representing the currents induced in a superconductor in the form of magnetic moments of these currents, which made it possible to simplify the analysis of the electromagnetic field in the generator without significant additional errors. As a result, the characteristics of the electromagnetic force longitudinal components and phase winding flux linkages versus the translator displacement have been obtained. The use of HTS inserts and a distributed winding in the stator made it possible to reduce the electromagnetic leakage losses and increase the interaction force between the stator and translator. However, since the additional outlays for the cooling system and thermal insulation of the HTS elements are commensurable with the generator cost, the obtained results on improving the power performance parameters do not allow an unambiguous statement to be made about the effectiveness of the considered technical solutions.

Frequent Observation

<p>Power plants are essential for modern life and blackouts are a frequent observation during natural disasters. Thus, assessing the specific hazards for power plant facilities is a crucial component of community risk management. However, multi-hazard assessments are rare and risk studies only rely on independent perils.</p><p>For the European power plant sites, a multi-hazard assessment has been taken out considering earthquakes, flood, tornados and lightning. Each peril is considered independently. For each power plant location, return period curves for the relevant impact metrics like ground motion or wind speed have been compiled based on a variety of hazard model inputs. Those curves have been combined to provide threshold exceedance curves for any multi-hazard combination.</p><p>The results have been facilitated within a software developed for the H2020 EURATOM NARSIS project (New Approach to Reactor Safety ImprovementS) to allow users to define relevant thresholds for different power plant system components like offsite power generators or the connecting road network. In addition, it allows to explore the site-specific hazard combinations. The tool is based on the Electron development framework.</p><p>This study provides a general overview on the multi-hazard situation of Europe’s primary power producers and highlights sites where multi-hazard combinations may lead to infrastructure disruption. The results come with an easy-to-use tool to quickly assess the relevant metrics. It is hoped that these findings can help to increase the overall resilience of the European power network.</p>

Piston Mechanism

Pneumatic mechanism widely used in industrial, automotive, aerospace, and etc. The principle of pneumatic like piston is move up and down due to the air pressure inside the piston. Mechanism of piston can be applied to the power plant that utilizes the ocean waves where as use of piston mechanism is very helpful in solving the problem of fossil fuel scarcity as a source of energy in power plants. In this study we will focus on the pneumatic system which utilizing ocean wave that moves longitudinally to encourage buoy that located on the piston shaft to up and down and then the pressing of air out of piston. Output of the piston will be forwarded to the generator (rotor and stator) to produce a voltage. In this paper is focused on the manufacture of pneumatic systems and processes to produce the rotation and voltage. Material of piston tube component made of aluminum and rubber, buoys made of plastic and generator such as of metal and copper coils. Output of the piston will be forwarded to the generator (rotor and stator) to produce a voltage.

Inefficient Operation

The operation of on-site power plants in the chemical industry is typically determined by the steam demand of the production plants. This demand is uncertain due to deviations from the production plan and fluctuations in the operation of the plants. The steam demand uncertainty can result in an inefficient operation of the power plant due to a surplus or deficiency of steam that is needed to balance the steam network. In this contribution, it is proposed to use two-stage stochastic programming on a moving horizon to cope with the uncertainty. In each iteration of the moving horizon scheme, the model parameters are updated according to the new information acquired from the plants and the optimisation is re-executed. Hedging against steam demand uncertainty results in a reduction of the fuel consumption and a more economic generation of electric power, which can result in significant savings in the operating cost of the power plant. Moreover, unplanned load reductions due to lack of steam can be avoided. The application of the new approach is demonstrated for the on-site power plant of INEOS in Köln, and significant savings are reported in exemplary simulations.

Modern requirements to the operational parameters of pre-start thermostating systems require a new approach to their creation or upgrading. Therefore, there is a need to consider the possibilities of using the combined power generation in pre-start thermostating systems. Launch vehicles include the equipment that requires certain temperature conditions for operation, which modifies its characteristics and disrupts normal functioning. The temperature also determines the characteristics of onboard power supplies, the reliability of the engine units and pre-start thermostating systems. For the normal functioning of pre-start thermostating systems, it is necessary to supply various combinations of power for the spacecraft. The recent open access publications were considered, including the combined types of power generation in pre-start thermostating systems. The thermostating systems of spacecrafts should have several sources of power, i.e. the combined power generation in pre-start thermostating systems has not been considered yet. The examination of the possibilities of using the combined power generation in pre-start thermostating systems. The thermostatic systems for performing the functions of pre-start thermostating systems are to have several sources of energy that will increase the reliability of their operation. Energy can also be supplied from an external source, which is essential for pre-start thermostating systems, especially in launch units. The possibilities of using the combined power generation in pre-start thermostating systems are considered, providing the reliability increase of their functioning. The application of mechanical, thermal, electrochemical and solar power plants, as well as the use of nuclear isotope and reactor power plants is suggested
