The Lian Dong U Valley Path Selection Of Power Transmission And Transformation Project

In line with the premise of the national laws and regulations of the system,how to choose a not only to meet the needs of enterprises and residents and can adapt to the conditions of the power system network from the outlet of substation to substation power line is in power transmission line project path optimization of basic meaning.In the process of selecting the line,it is not only to take into account the low cost,convenient construction,power supply reliability,but also to take care of the comprehensive environmental impact problem,can not produce adverse effects on the surrounding industries,can not cause pollution to the natural environment,can not destroy the sustainable development of ecological environment.On the basis of this,the design scheme of the optimal route is sought.Previous means of science and technology level is low,power transmission project line selection often use the line field area measured by topographic surveying and mapping technicians,precisely label starting point and ending point between terrain physiognomy condition,then by engineering design personnel on the topographic map based on experience determine the reasonable line path,path to determine the basic,then visit a path through the various territorial ownership units,in consultation with the were signed various types of the compensation agreement,the implementation of the feasibility of the path to finalize the implementation path of the program.Traditional methods can not quickly select the best path,and only by the experience to judge it is easy to choose a line of subjective errors,resulting in land acquisition area is too large,across the obstacles to the cost of a higher level of error,not only affect the regional overall ecological environment,but also create huge waste of resources.Author of existing a large number of power transmission project path optimization literature in-depth studies,comparison of various path optimization algorithm,with a total weight of find using the improved ant colony algorithm as the basic algorithm of path optimization,and were optimized using this algorithm couplet east U Valley 35 kV special substation power transmission project path,model,obtains the optimal route.The author compares the optimal path of the optimal path with the traditional method,and shows the excellence of the new technology and new method.
