Title: Pros and cons of power combined cycle in Venezuela

Abstract

In Venezuela combined cycle power has not been economically attractive to electric utility companies, mainly due to the very low price of natural gas. Savings in cost of natural gas due to a higher efficiency, characteristic of this type of cycle, does not compensate additional investments required to close the simple cycle (heat recovery steam generator (HRSG) and steam turbine island). Low gas prices have contributed to create a situation characterized by investors` reluctance to commit capital in gas pipe lines and associated equipment. The Government is taking measures to improve economics. Recently (January 1, 1997), the Ministry of Energy and Mines raised the price of natural gas, and established a formula to tie its price to the exchange rate variation (dollar/bolivar) in an intent to stimulate investments in this sector. This is considered a good beginning after a price freeze for about three years. Another measure that has been announced is the implementation of a corporate policy of outsourcing to build new gas facilities such as pipe lines and measuring and regulation stations. Under these new circumstances, it seems that combined cycle will play an important role in the power sector. In fact, some power generation projects are consideringmore » building new plants using this technology. An economical comparative study is presented between simple and combined cycles power plant. Screening curves are showed with a gas price forecast based on the government decree recently issued, as a function of plant capacity factor.« less

  • The energy crisis of the 1970s has lead to a demand for increased regulation of the energy sector by certain governments for several reasons. Increased regulation is viewed as a means of assuring access to alternative energy sources for all people. This is the welfare argument. Regulation is also viewed as a means of rationalizing the system of energy delivery. This is the efficiency argument. Under this traditional view of regulation the prices and profits of the regulated energy industry are expected to be lower and the allocation of energy sources more efficient. However, this traditional view of alternative energymore » source regulation is not without flaw. Firms of the energy producing industry can use several methods to ''capture'' established regulatory agencies and ''force'' them to ''regulate'' the dissatisfaction of the general public rather than the behavior of the firms. As a result, regulatory agencies can formulate decisions that are approximate to what the regulated energy industry desires instead of what the public expects. This paper will apply the arguments of the capture theory and the theory of political-economy for regulatory agencies in the alternative energy sources sector. Further, it will analyze a firm's behavior under uncertainty about demand and cost conditions. These conditions make it difficult for regulatory agencies to force a monopoly to make competitive investment and output decisions. Finally, it will discuss some of the problems associated with cost-benefit analysis which is widely used by regulatory agencies in their decision-making process.« less
  • The design of cryogenic linacs is a challenging engineering task; however, significant improvements in accelerator performance are possible. Resistive power losses may be reduced by a factor of four or greater. Greater flexibility is possible in thermal management as a result of substantial increases in thermal conductivity for certain materials. Radio frequency structures may be an order of magnitude more stable in terms of frequency shifts due to thermal transients resulting from very small coefficients of thermal expansion at cryogenic temperatures. Significant engineering problems must be addressed, such as the design of effective rf contacts that will not be affectedmore » by thermal cycling and the design of cryogenic mechanisms and dynamic components, such as frequency tuners, that operate reliably at cryogenic operating temperatures. The areas of high-power sparking and multipactoring have not yet been experimentally addressed. Both Los Alamos, Grumman Aerospace Corporation, and Boeing Corporation have built or are building and testing cryogenic accelerator structures. This paper will review the advances made in cryogenic technology applied to radio frequency quadrupole (RFQ) and drift tube linac (DTL) structures and will discuss the advantages and engineering challenges that these linacs present.« less
  • There is a new magnetic alloy called Finemet which has very constant {mu}'{sub p}Qf up to {approximately} 2 kG and is very stable at high magnet flux density and temperature. It may be a good can-didate for high-gradient rf cavities. However, it has a rather low quality factor and is therefore very lossy. We compare the pros and cons of Finemet versus the common ferrite, when used in low-energy accelerating cavities, insertion for space-charge compensation, and barrier cavities.
  • This paper addresses the problems and benefits of microprocessor based metering systems for electric power. The topics of the paper include historical aspects of power metering, mechanical meters, operating environments of power meters, reliability, cost, industry and customer acceptance, service life, and ease of adaptability to new rate structures.
