In light of China s Ninth Five-year Plan (1996-2000) for Electric Power Industry & the Long Term Targets by the Year 2010, the paper considers the strategy for developing China's thermal power in the 21st century shall be the efficiency and cleaning technology of coal use. Especially important is the structure of power sources and configuration of technology process, and secondly the implementation of energy saving and environmental protection ideology in the various stages of thermal power construction and design work.  相似文献

California's restructuring stripped utilities of responsibility for retail customers' electricity resource portfolios, leaving most of the state exposed to intense spot market volatility. Subsequent experience reinforces the need for all states to redefine a regulated portfolio management function.  相似文献

The connotation of "incest" in Quentin’s narration goes beyond what Faulkner would admit. It reflects not only the complex relationship between Quentin and his sister Caddy, but also the angst the protagonist feels in pursuit of inf initude.  相似文献

The lowest societal costs in metering, billing, and information systems would be incurred if local distribution companies continue to meter and bill all their customers. Also promising is the complete transfer of those functions to a third party that provides services to several local distribution companies and energy service providers within a jurisdiction, thereby avoiding redundant systems and costs.  相似文献

Results from studies of the water chemistry used in the system for cooling the stator windings of alternators used in supercritical-pressure power units are presented, and a solution is suggested using which the standardized pH value of cooling water is maintained in the range 8.0–9.0. It is shown that addition of NaOH in the water cooling system when a drop of pH value occurs cannot fully satisfy the requirements of the operating circular due to low buffer properties of aqueous medium.  相似文献

On October 20, the State Grid Corporation (SG) released transaction information in electricity market for the first three quarters of 2006 within the area covered by the corporation. It showed that in the first three quarters, the volume of trans-regional electric energy trade of SG amounted to 85.12 TWh, increasing 17.1% over that of the corresponding period last year. The volume of inter-provincial exchange was 111.4 TWh, increasing 13.68%. Power purchased by SG from generation enterprises amounted to 1243.924 TWh, up 13.04% on a year-on-year basis.  相似文献

The GTD diffraction coefficients for the half-planes edge are obtained by a new semi-analytic approach: From the modal expansion of the Greens function of an acoustically soft or hard wedge the total field due an incident plane wave is derived by locating a line source at infinity and by transforming the incident line-source field to an incident plane-wave field. By means of the second Greens theorem and by using the bilinear form of the free-space Greens function, the scattered far field is obtained from the exact field values on the wedges flanks. The isolated edge-diffracted part can be identified as the difference between the far field scattered by a half plane and one half of the far field scattered by the entire plane. The obtained alternating and —in the classical sense— non-converging series are numerically evaluated by means of a linear (consistent) summation technique, and the comparison to Kellers result shows excellent agreement. The main advantage of this new method is that it can be applied to a certain class of more difficult problems (circular and elliptic cone, plane angular sector, etc.).  相似文献

For our research, which aims to provide a thorough approach to assessing the development of the retail electricity market in the EU, we tested the hypotheses that the number of suppliers in the retail markets of EU member states has increased significantly over the past decade, and that in the same period, the number of suppliers entering the retail markets of EU member states increased significantly with market liberalisation. We also collected data on the number of electricity suppliers to end-consumers in EU member states between 2010 and 2017, and used the Kruskal-Wallis test for verification, which was also used to establish the ratio between electricity consumers and suppliers between 2010 and 2017. A thorough overview of current scientific findings led us to contemplate a possible combination to measure the dynamics and assess the energy market development, since several authors indicate that no method has been fully accepted as standardised for a thorough assessment of the energy market development. Therefore, a combination of indicators to measure the dynamics and assess the energy market development is proposed in the conclusion of this article, which brings important implications for science and specifically for politics and experts.  相似文献

In July 2021, the United Kingdom (UK) Government considered tripling the UK grid’s performance-based incentive scheme’s penalty for capacity non-delivery during a shortage. This paper proposes an insurance that a generator may buy to manage its risk exposure to the scheme’s penalty. It also shows how to use readily available data to calculate the insurance’s per MW premium. These findings suggest that the proposed insurance deserves consideration by generators and insurance sellers.  相似文献

“7·30”大停电暴露出印度在电源发展、电网发展、网架结构、体制管理、一次能源、环保约束、市场经济、信息技术等方面给电力系统可靠性埋下的隐患及在停电灾难中的推波助澜。这些因素像物理电网的输电阻塞一样,影响供电充裕性和安全性,不妨称为广义阻塞。各参与方藉此谋取利益的博弈又往往加剧这些广义阻塞。从这个视角反思印度停电灾难的必然性、实际触发事件的偶然性,以及停电演化过程的内在规律;研讨对中国的启示;探索中国减少大停电风险的措施;指出坚强智能电网在保障大能源安全与环境安全中的作用。  相似文献

China covers a vast territory with many rivers and richhydropower potential.China's exploitable hydropowercapacity amounts to 378 GW which corresponds to an annual powergeneration of 1920 TWh.This makes China the leading country inthe world as far as hydropower resources are concerned.At the end of 1990,the country's hydro capacity developedwas 36.0 GW,accounting for 26.1% of the country's total,with anannual electricity production of 126.4 TWh,accounting for almost20.34% of the country's total.By the end of this century,China's hydropower capacity willreach 75-80 GW,constituting 19.8-21.1% of the country's  相似文献

Results obtained from upgrading the flow paths of the low-pressure cylinders of OAO Turboatom K-500-6.4/3000 steam turbines installed at the Kursk, Smolensk, and Leningrad nuclear power stations are presented. With the annular area of steam outlet from the last stages increased from 6.3 to 8.19 m2, it became possible to reduce the loss due to outlet velocity by a factor of 1.8 and increase the turbine power output by 16MW, which is equivalent to increasing the power unit efficiency by 3.2%.  相似文献
