Application of Differential Pressure Transmitter in Hydroelectric Power Station

Differential pressure transducers play a crucial role in the control of hydroelectric power stations, which mainly involves the measurement of parameters such as water level, flow, and pressure.

In hydropower plants, it is essential to monitor accurately changes in reservoir water levels. Digital differential pressure transmitters need to be installed upstream and downstream of the reservoir to monitor changes in water level in real time by measuring the difference in water pressure upstream and downstream of the water surface. This data is used for reservoir level control to ensure that the water level fluctuates within a safe range to avoid floods or droughts.

Hydroelectric power plants need to control water flow rationally based on conditions such as power demand and reservoir levels. Dp pressure transmitters, in conjunction with piping and flow rate sensors, can measure the pressure difference in a water stream to calculate the actual flow rate of the stream. This data is used to optimize generating unit output and water flow control to maximize the use of hydro energy resources.

Dp transmitters can also be used to monitor the inlet and outlet pressures of turbines and pumps. By measuring pressure differentials, operators can keep abreast of the equipment's condition, thus ensuring that it operates within its normal range. Abnormal pressure variations may suggest equipment failure or operational problems that require timely intervention.

In the event of large-scale rainfall or other flood risks, high accuracy differential pressure transmitters can be used to monitor changes in upstream and downstream water levels to predict flooding. This data can help operators take emergency measures, such as adjusting sluice gate openings and releasing reservoir levels, to minimize the impact of flooding on the hydropower plant and surrounding areas.

Through long-term monitoring of water level and flow data, the dp transducers helps managers better grasp the water resources of the reservoir, allowing for more precise scheduling and management, balancing the needs of power generation, navigation, ecology, and many other needs.
