Power Generation System

This project presents the design of an electrical power generation system, which takes advantage of a person’s movement when exercising on a static bicycle. This system is implemented in a gym located in Suchiapa, Chiapas. The analysis is carried out of three categories of people: high performance athlete, occasional athlete and sedentary person, to evaluate the calories consumed per day and exercise time on static bicycle. This information provides an estimate of the energy generated in one day, to compare the receipt of power consumption of CFE before and after the system. The static bicycle is mechanically attached to a generator by means of a support, followed by a diode allowing the passage of the electric current with characteristics similar to a switch, which is connected to a voltage regulator that maintains a constant voltage level. The regulator is coupled to the electric accumulator and an inverter. The latter is in charge of converting the direct current input voltage and alternating current output. By implementing the mechanism with nine static electric bicycles, an energy saving of 17.57 % is obtained.

Integration Strategies

Solar aided coal-fired power generation system (SACFPGS) combines solar energy and traditional coal-fired units in a particular way. This study mainly improves the solar thermal storage system. Genetic algorithm is used to optimize the SACFPGS. The best integration approach of the system, the collector area, and the corresponding thermal storage capacity to replace each high-pressure extraction are obtained when the amount of coal saving in unit solar investment per hour is at its largest. System performance before and after the improvement is compared. Results show that the improvement of the thermal storage system effectively increases the economic benefit of the integrated system.

Fortunately traditional reliability theory, where the system and the components are always described simply as functioning or failed, is on the way to being replaced by a theory for multistate systems of multistate components. However, there is a need for several convincing case studies demonstrating the practicability of the generalizations introduced. In this paper an electrical power generation system for two nearby oilrigs will be discussed. The amounts of power that may possibly be supplied to the two oilrigs are considered as system states.

System States

The basic multistate reliability theory was developed in the eighties and the beginning of the nineties, replacing traditional reliability theory where the system and the components are always described as functioning or failed. In Natvig et al.10 the theory was applied to an electrical power generation system for two nearby oilrigs, where the amounts of power that may possibly be supplied to the two oilrigs are considered as system states. However, there is still a need for several convincing case studies demonstrating the practicability of the generalizations introduced. In the present paper the theory is applied to the Norwegian offshore gas pipeline network in the North Sea, as of the end of the eighties, transporting gas to Emden in Germany. The system state depends on the amount of gas actually delivered, but also to some extent on the amount of gas compressed mainly by the compressor component closest to Emden.
