用于监视的建模 - 当毫米很重要时

抽水蓄能水电站之一various ways of extracting energy from water. The biggest hydropower energy sources in Lithuania are the Kaunas Hydropower Plant and the Kruonis Pumped Storage Hydroelectric Plant (KPSHP). The KPSHP is a pillar for the Lithuanian energy system that has been successfully supplying energy to homes and businesses for more than 20 years. Located close to the city of Kaunas, this state-of-the-art energy facility is the one of the biggest plants of its type in the Baltic region.

This 900 Megawatts hydroelectric plant is designed to generate electricity, balance consumption by regulating voltage, frequency and load fluctuations, and compensate energy deficiency in case of an emergency situation. According to Lietuvos Energijos Gamyba, the KPSHP covers 6 per cent of Lithuania’s total electricity demand and is capable of ensuring 94 per cent of the total necessary energy reserves for Lithuania in case of emergency – a deformation in its structure can be fatal to Europe’s Baltic state energy system.

高科技进行大坝监控

为了监视KPSHP，UAB SmartOffice使用Leica Nova MS60多稳态对水力发电厂进行了调查，以收集测量值和结构的点云。收集的3D数据允许UAB SmartOffice分析表面并计算水力发电工厂的垂直性。用点云生成的模型还将作为未来扫描的参考，该扫描将监视大坝的当前状况和变形。

“使用Leica Nova MS60多个扫描带来的结果超过了预期。除3D扫描最多1,000米外，主要的好处是节省时间，准确性和简单性。” UAB SmartOffice总经理乔纳斯·瓦尔纳斯（Jonas Varnas）说。“使用MS60与使用TPS的例程一样简单，但是将TPS测量的精度和3D扫描结合到一个系统中。”

借助MS60多稳定，可以在一个视图中使用覆盖的测量点和3D模型来调查复杂的站点，从而使用户可以执行垂直性和变形检查，以更可靠，更快，更完整的方式识别损害和缺陷。自学习跨性别的3D扫描功能可帮助用户扩展其提供的服务组合，并能够使用：

• construction monitoring
• quality inspection
• clash detection
• as-built Building Information Modelling (BIM)

KPSHP通过岩土传感器监测，因此不使用大地设备。与其他传感器技术相比，变形信息仅限于几个点，MS60多稳态提供了测量密集量的点的能力，并通过覆盖的TPS测量值对数百万点的位移进行测量。

Inspecting and comparing surfaces

使Kruonis植物与众不同的原因是它在需求低时期或作为传统的水力发电厂在白天提供正常能源需求的传统水力发电厂的能力。

These water level changes in the upper reservoir of the dam can cause deformations. The KPSHP authorities, therefore, were interested in analysing the surface and verticality of the dam, identifying places with deformation and comparing the scanned model with the ideal model.

3D Reshaper, an essential software for surveyors working with point clouds, allowed UAB SmartOffice to measure, inspect and compare surfaces displaying deviation information with millimetric accuracy. The modelled surface generated from the point cloud provided an accurate representation of reality to detect millimetric changes in shape for the entire structure.

Varnas说：“ 3D Reshaper允许我们进行最佳的形状导出，通过几种集成工具分析表面，并允许我们的客户以非常清晰的方式检查表面 - 正是我们的客户正在寻找的东西。”

监视事项

在大坝监测中，需要毫米精度。这些结构中结构变形的后果超出了数百万个成本。因此，应及时发现和监测变形，以确保安全操作和使用以及具有成本效益的构造和管理。
