Turbine Efficiency Monitoring

TEMS is used in a portable mode or as a permanently installed system for measurement of hydro turbine (or pump) efficiency. The system collects data from the flowmeter, power meter and pressure sensors and computes unit efficiency in real-time. The system is used to improve plant operation and to provide contractually accepted pre- and post-upgrade performance data, and is designed to meet ASME PTC-18 and IEC Pub. 41 codes.

The Accusonic Model 7530 Flow-Efficiency Monitoring System Delivers Information to Maximize Plant Efficiency.

Flow-Efficiency Monitoring System Accusonic Model 7530 measures…

on-line individual unit and total plant discharge and efficiency. The system provides the operator with this data in addition to best gate and historical best combinations of gate settings. This allows the plant engineer or operator to increase unit and plant efficiency based on actual measured performance.

Measures Efficiency…

The 7530 measures flowrate and accepts inputs from power output (MW), pressure and level sensors to compute individual unit and total plant water-to-wire efficiency. Up to 6 turbines can be simultaneously monitored with one 7530. Pumping mode efficiencies are also determined for pumped-storage hydro plants. Stored data is easily retrieved to analyze plant operation, detect trends, and evaluate unit upgrades.

Provides Current Unit MW per CFS…

Accusonic Technologies has added a feature requested by many plant owners. Display (and data storage) of MW/CFS (or cms) challenges operators to set unit gates at or near their point of highest efficiency, resulting in higher plant efficiency. This feature can be configured on-site to display revenue (income dollars per cfs). The Accusonic Model 7530 Flow-Efficiency Monitoring System Delivers Information to Maximize Plant Efficiency.

Provides Operators with Historical Best™ Gate Combinations…

The Historical Best™ feature allows the operator, with one keystroke, to view the highest efficiency achieved for a given plant output, and what gate settings were used to achieve it. Optimum gate combinations can be determined for easy reference, giving the capability to improve upon traditional dispatch strategies. The Historical Best™ feature also provides the highest efficiency achieved for individual units, and what flow, power and gate settings were used.

Measures Flow…

The 7530 is an expansion of our Model 7500 flowmeter and contains all of the features and capabilities of this widely used flowmeter system. The 7500 is the hydro industry standard acoustic flowmeter system designed for permanent hydroplant operational use and ASME PTC 18/ IEC Pub 41 test programs.

The system simultaneously measures flowrate in multiple penstocks or intakes and is described in detail in our Model 7500 brochure. Existing Model 7500 flowmeters can be upgraded to the Model 7530
