Process instrumentation for power industry

Process instrumentation plays a crucial role in the power industry by enabling the analysis, measurement, and control of various industrial process parameters. As power technology suppliers, both SenTec and Siemens, offer a wide range of process instrumentation and analytics solutions tailored for the power industry.

Coal power

SenTec is an experienced supplier of process instrumentation for coal power industry. The process instrumentation and analytics sensors for level, flow, pressure, temperature measurement are optimized and certified for use in the energy sector.

Typical application scenarios

Level measurement and limit measurement on coal bunkers

In coal-fired power plants, lignite and anthracite are temporarily stored in bunkers up to 30 meters high. In order to ensure uninterrupted transportation of coal conveyor belts, safe and reliable level measurement is indispensable here. The additionally installed limit detection instrument is used to prevent the coal bunker from overflowing.

Measuring pressure, temperature and flow in water and steam pipelines

In a steam cycle, pressure flow and temperature must be monitored at different points in the process. Especially reliable measured values are required at the turbine inlets of different pressure classes.

Measuring oil level in turbine room oil sump

Turbines are highly complex systems in which lubricants play an important role. Lubricating oil keeps the turbine running properly, keeps maintenance costs to a minimum and prevents turbine downtime. Turbine oils are derived from the highest quality mineral oils, which have special properties in terms of anti-emulsification (separation of water) and degassing. The oil level in the oil reservoir must be monitored to ensure there is always enough lubricating oil.

Level measurement at conveyor belt transfer stations

In coal-fired power plants, anthracite or lignite is burned as the main fuel. The coal is conveyed to the combustion furnace by different conveyor belts. Level measurement is necessary to prevent back-blocking or overflows at transfer stations on conveyor belts. Uninterrupted feeding of the furnace is only possible if the level is reliably measured at the conveyor belt transfer station.

Hydroelectric power

Hydroelectric power refers to the generation of electricity using the force of flowing water. It involves damming up a river or creating a reservoir to store water, which is then released through penstocks to drive a turbine.

Typical application scenarios

Flow measurement at the dam

The seepage water in the dam of the hydroelectric plant is collected in pipes or channels. The quantity of seepage water provides information on the condition of the dam (another indicator of the condition of the dam is the clouding of the seepage water which is also assessed). The quantity of water flowing in an open channel is measured via water head height as it passes through a ‘V’ notch, flume or weir structure, which is then calculated into flow rate.

Level measurement at the reservoir

Pumped storage power plants store a large amount of energy and feed it into the grid very quickly when necessary. One important parameter is the height of the water level in the reservoir. It allows calculations to be made about the amount of energy available and the existing storage volume in pump operation mode. High reliability is required from the measurement technology deployed, because the sensors are often mounted at very remote locations.

Level temperature measurement and point level detection in a seepage water shaft

A large number of sensors are deployed to ensure reliable operation of the generators and turbines in the hydroelectric power plant. They monitor the pressure in the hydraulic lines, the lubricant supply for turbine bearings, vibration, temperatures and many other parameters. At the lowest point of the plant, cooling water from the generators and any leakage water from the Kaplan or Francis turbines is collected in a seepage water shaft, pit or sump. To prevent a flooding of the shaft and thus of the turbine building, with disastrous results for equipment, the sensors are often installed redundantly. As additional protection, the maximum water level is monitored with a point level switch.

Pressure and flow detection of pressure pipelines in hydropower plants

In a hydroelectric power plant, water is conveyed from the dam to the turbines through penstocks. A partial or complete rupture of a pressure line can increase the flow in the line beyond the maximum flow. If the leak goes undetected, it can cause floods and destroy power plants, resulting in lost production. Therefore, it is important to measure the flow reliably in order to detect if there is a rupture in the pipeline and then take the necessary action, such as closing the pressure valve.
