计算煤立方米

案例分析

发电是国家经济增长和福祉的最关键组成部分之一。由于经济的加速扩张和全球能源需求的增加,印度是world's fastest growing energy markets. Although the power sector is diversified in this South Asian country, 62 per cent of India's electricity demand is met through the country's vast coal reserves.

Sembcorp是在全球五大洲运营的领先能源,水和海洋集团,于2010年进入印度能源市场。该公司现在负责造成3500兆瓦的运营能力和七兆瓦的可再生能源资产,并在七兆瓦中开发了七兆瓦状态。作为Sembcorp的一部分,印度Thermal Powertech Corporation(TPCIL)运营印度的1,320兆瓦燃煤沿海电厂.

TPCIL的热电厂专家在过去的常规测量方法中使用,以找出煤桩的坐标和形状。每个季度对煤炭存储场进行调查以进行身体验证是一个巨大的挑战。使用Leica Nova MS50多阶段,测量煤炭桩的确切特征的挑战属于过去。

在3D环境中捕获现场条件是计算量并确保直接在现场最佳控制的最有效方法。该公司使用世界上第一个自我学习的跨越,捕获了股票的准确概况和数量,并在和解过程中验证了数量。

一个小variation in volume accuracy would lead to tonnes and tonnes of coal deviation in physical stock quantity. Accuracy in the measurements is, therefore, one important benefit TPCIL valued when capturing the profile volume of the coal stock piles.

“我们选择Leica Multistation MS50,而不是总站,因为我们能够实现煤炭库存船坞的准确量,并且使用Leica Infinity软件,报告生成过程更容易。节省时间和成本是该项目的主要因素之一。可以使用MS50来实现优化的煤炭量计算,”TPCIL运营助理经理Nandagopal Kesavan说。

对大约600,000 - 80万吨煤炭储藏场进行的物理验证调查,用于使用常规测量方法需要7到10天。使用MS50,可以在两天. Surveyors were able to see all setups merged flawlessly directly on the unit and determine the scan quality in the field right on the instrument.

Experts processed the information with Infinity geospatial software, allowing to work with the scanned point data and manage data in the 3D viewer.


An ongoing job



煤炭调查项目始于2015年7月,每季度每年都在继续。TPCIL从国际和国内煤矿接收煤炭,并进行煤炭库存物理验证测试至:

  • Ensure book stock and consumption of coal is matching with the physical stock available on date;
  • 即使书籍股票足够多,也可以在物理上可获得足够的国内和进口煤炭库存;
  • Calculate the amount of coal loss during the conveying by matching the ship vessel draft survey report with the physically verified stock available for the ship consignment.

呈规则提供了一个针对煤炭量计算优化的技术解决方案developed for this project and for the company.

Given the success with the MS50, Sembcorp has procured another MS60 for coal volume estimation.
