gui chao cable news: wind farm collector line path selection (cable)

as a part of the wind farm design, the choice of the route is very important for the overall design of the circuit.
whether the path is right or not will affect the safety, economy and rationality.
the scheme is more inclined to the northern part of the meteorological environment simple,
the cable scheme is widely used in the south china area where the weather conditions are complex and changeable, and the areas with special requirements of environmental protection.
talking about the route choice of cable scheme.
path selection should follow the following principles:
1, cable path to short.
whether it is an overhead line or a cable line, "short" is definitely one of the determinants of the economic performance of the transmission line.
of course, the so-called short, is to combine the actual situation of the site, the path selection.
cable lines are not as good as the overhead line can go straight line".
because the cable laying is underground, and most of the wind farm where the terrain, topography is more complex,
so short path often means high cost. of course, if the cable lines in qinghai it is another matter.
at present, the cable route of the wind farm is more of the scheme of laying along the road, although it is not the shortest path in theory,
however, combined with safety, economy, rationality and post construction factors,
the scheme of laying along the road is undoubtedly the most short path of the mountainous terrain wind farm.
2, avoid crossing with other pipelines.
at present, most of the domestic wind farm is far away from the city,
under normal circumstances, there will be no intersection with other pipelines. but this is still the case,
for example, oil pipelines, heat pipes, etc.. encounter this situation,
if can through the short distance to avoid detours the pipelines is best.
if you can not avoid the cross, you need to meet the requirements of the relevant norms of distance and do the corresponding protection measures.
3, to avoid the need to plan the construction of the place.
and the same as the bar, such a situation rarely occurs, but if you need to plan the construction of the place,
in the path of the program should be reasonable to avoid, to avoid subsequent line failure caused by construction, resulting in unnecessary losses.
4, easy to construction and maintenance.
as far as possible to choose a convenient route cable lines, cable lines will be set up along the inspection wells,
in case of failure, wind farm operators can quickly reach and deal with.
prior to the mountain wind farm cable laying along the road program, but also fully embodies this point.
5, the cable is damaged (mechanical, chemical, water and soil, underground current corrosion, ant pest and so on).
as a kind of underground engineering, there are many uncertain factors in cable laying,
combined with the actual situation of the scene as far as possible to avoid the impact of the above factors.
if you can not avoid, should choose to meet the requirements of the actual situation of the cable and do the relevant protection measures.
6, not close to flammable and explosive materials and other heat sources.
these are the principles of the wind farm cable route options to share with you.
of course, when the wind farm route choice, not empty theory on paper,
must be combined with the actual situation of the site. combining theory with practice, we can choose a safer, more economical and reasonable route.
