Calculating coal cubic metres

发电是最关键的混合涂料之一nents for the economic growth and wellbeing of nations. Due to accelerated economic expansion and increase in global energy demand, India has one of the世界上增长最快的能源市场。尽管在这个南亚这个国家，电力部门多样化，但通过该国庞大的煤炭储量满足了印度62％的电力需求。

Sembcorp, a leading energy, water and marine group operating across five continents worldwide, entered the Indian energy market in 2010. The company is now responsible for thermal and renewable assets accounting for more than 3,500 megawatts of power capacity in operation and under development in seven states. As part of Sembcorp, Thermal Powertech Corporation India (TPCIL) operates a1,320-megawatt coal-fired coastal power plant in India。

Thermal power plant specialists at TPCIL used in the past conventional surveying methods to find out the coordinates and shape of the coal piles. Surveying the coal storage yard every quarter to do the physical verification was a big challenge. Using Leica Nova MS50 MultiStation, the challenges of measuring the exact profile of the coal piles belong to the past.

用点云扩大可能性

Capturing the site conditions in a 3D environment is the most effective way to calculate volumes and ensures best quality control directly in the field. Using the world’s first self-learning MultiStation, the company captures the accurate profile and volume of the stock and verifies the quantity during reconciliation.

体积准确性的较小变化将导致物理库存数量的煤炭偏差和吨偏差。因此，测量中的准确性是捕获煤炭堆堆的剖面量时的一个重要好处TPCIL。

“We choose Leica MultiStation MS50 instead of a total station because we were able to achieve the accurate volume of the coal stock yard, and the report generation process is easier using Leica Infinity software. Time and cost saving was one of the main factors in this project. Optimised coal volume calculation can be achieved using the MS50,”said Nandagopal Kesavan, assistant manager of operations at TPCIL.

The physical verification survey of approximately 600,000 – 800,000 tonnes of the coal storage yard used to take seven to 10 days with conventional surveying methods. Using the MS50, the same work can be done intwo days。测量师能够看到所有设置都直接在设备上完美合并，并确定仪器上现场的扫描质量。

专家使用Infinity Geospatial软件处理了信息，可以使用扫描的点数据并管理3D查看器中的数据。

一项持续的工作

The coal survey project started on July 2015 and has been continuing every year once a quarter. TPCIL receives coal from international and domestic coal mines and does the coal stock physical verification test to:

• 确保账面库存和煤炭的消费与日期可用的实物库存相匹配；
• 确保足够的国内和进口煤炭股票is physically available even when book stock shows sufficient amount;
• 通过将船舶船只草案调查报告与可用于船舶货物的物理验证的股票相匹配，计算传送过程中的煤炭损失量。

地理系统提供了technical solution optimised for coal volume calculation为该项目和公司开发。

鉴于MS50的成功，Sembcorp购买了另一项MS60以进行煤炭量估算。
