作者 赵伯和 《水产科技》 2003年第5期26-26,共1页
目前捕捞养殖对虾的电网有一定的优越性,在对虾养殖业上有较广泛的应用。如对虾养殖成熟收获,大多采用脉冲电网进行捕捞收获。在对虾养殖过程中,起捕标粗虾苗进行分塘疏放,因虾塘底质受污染老化,水质败坏变劣,要起捕幼虾或中成虾进行换... 目前捕捞养殖对虾的电网有一定的优越性,在对虾养殖业上有较广泛的应用。如对虾养殖成熟收获,大多采用脉冲电网进行捕捞收获。在对虾养殖过程中,起捕标粗虾苗进行分塘疏放,因虾塘底质受污染老化,水质败坏变劣,要起捕幼虾或中成虾进行换塘,另行投放等,也有用脉冲电网进行起捕操作。尤其是当今,经多年高密度的人工养殖对虾,受污染老化的虾塘越来越多,越来越严重, 展开更多

The power/energy losses reduction in distribution systems is an important issue during planning and operation, with important technical and economical implications. Thus, the energy losses minimization implies not only the technical improvement of the network, through its renewal with the introduction of the technological innovations in the equipment and circuit components as well as the optimal planning of the design and development of the network, but also requires the use of the methods and software tools to facilitate the operation process. The paper presents a strategy for power / energy saving which is replacement of the 6 kV voltage level with 20 kV voltage level. In this line, different urban distribution networks were analyzed using fuzzy techniques for load modeling. 展开更多
