  • A Comprehensive Economic Benefit Evaluating Method of Grid-connected Wind Power Generation under Demand Response
    Energy Procedia, 2017
    Co-Authors: Ya Liu, Yi Wang
    Abstract:

    Abstract The phenomenon of abandoning wind Power in China is very severe. Promoting the demand side response management vigorously become the key measures in North China. Overall efficiency evaluation of the wind farm connected with grid under demand response is necessary to solve the problem. At the same time National Energy Board of China called for a full launch of the carbon emissions trading in 2017. The carbon-emissions reduction is conducive to both environmental protection and economic benefits increasing. This article analyses six aspects of economic efficiency and low carbon benefits of the impact on the system, including the wind Power Station Construction, operation and maintenance, scheduling cost of demand response, generation benefit, peak-load following benefit and network loss improvement benefit. Taken low carbon trading regulations as the basis, the paper come up with the establishment of a comprehensive economic benefits model in carbon emissions trading mechanism with comprehensive economic benefits of the system. The overall test system is quantified through calculation, which proves the validity of the evaluation method.

  • saw cold wire technology economic alternative for joining hot crack sensitive nickel base alloys
    2008
    Co-Authors: Uwe Reisgen, Ulrich Dilthey, I Aretov
    Abstract:

    The Construction of industrial plants and gas turbines makes increasingly higher demands to the used materials. Consequently, austenitic CrNi-steels and nickel-based alloys are increasingly applied in Power Station Construction, crude oil and petrochemistry and, moreover, in industrial furnace and turbine Construction. Besides the good mechanical properties of these materials also a good process ability is required. This applies particularly to welding. Due to their low heat input, TIG and MIG (pulsed) welding are the most frequently used welding methods in the case of heat-resistant nickel-base super alloys and also in the case of stainless CrNi-steels. Due to the high heat input, submerged-arc welding is, as a rule, not applied for the welding of these steels. Submerged arc welding could, however, be used as efficient alternative if process modifications are available, which ensure higher hot cracking resistance by reduced heat input. Apart from the high weld quality which is a result of submerged-arc welding, the economic efficiency which is particularly marked by the high deposition rates is also interesting.

  • Developing and practice of QLY2150-full circle slewing and tyre type crane for erecting wind Power Station
    Engineering Sciences, 2010
    Co-Authors: Ndf Heavy-industry
    Abstract:

    The paper briefly introduced internal and external situation about the wind Power Station Construction and the newly developing plan for the wind Power Station Construction of our country firstly;and then in detail introduced the general scheme,key techniques,new inventions and realizing methods about the developing subject of QLY2150-full circle slewing and tyre type crane for erecting wind Power Station which proposed based on the above situation;finally introduced the states of the prototype be used in Construction of wind Power Station,and pointed out some great superiorities of this new crane compared with the other general tyre cranes,tuck cranes and crawler cranes.
