Embodiment 1

[0038] Embodiment 1: as figure 1 As shown, a water level measurement method of a hydropower station is used to monitor the water level of a hydropower station. Two hydraulic sensors are placed at different depths under the liquid surface of a hydropower station. Environmental effects on two hydraulic sensors. The real-time depth information of different depths under the liquid surface of the hydropower station is collected through two hydraulic sensors A1 and A2. Preferably, the distance between the two hydraulic sensors is 1.5 meters, and other values ​​greater than 1 meter and less than 2 meters are also acceptable, but the real distance must be measured accurately. The two hydraulic sensors can be connected together by a plastic hard strip to prevent the wave Floats under impact.

Abstract

The invention provides a method for measuring the water level of a hydropower station. Two hydraulic sensors are used to measure the water level of the hydropower station at the same time. The data measured by the two hydraulic sensors are first limited and filtered, and then digitally low-pass filtered. Depth deviation rate, and finally calculate the water level of the hydropower station according to the deviation rate, so as to ensure the measurement accuracy. The invention also provides a water level monitoring system of a hydropower station. When the water level values ​​measured by the two hydraulic sensors have large deviations, it means that one of the hydraulic sensors has insufficient measurement accuracy and needs to be adjusted or replaced. It avoids the problem that the measurement results are gradually reduced due to equipment aging due to long-term use when there is only one hydraulic sensor, and it is difficult to find problems.

Description

technical field [0001] The invention relates to the field of water level measurement, in particular to a water level measurement method for a hydropower station and a water level monitoring system for a hydropower station. Background technique [0002] The energy difference per unit weight of the water body between the upstream diversion inlet section of the hydropower station and the downstream tailwater outlet section, usually measured in meters. It is generally represented by the water level difference between the two sections, which is called the gross head of the hydropower station. This is an important parameter for adjusting the turbine operation of the hydropower station. In water conservancy projects, water level measurement has always been the focus of reservoirs. In the event of floods, typhoons and other abnormal weather conditions, if there is no stable and reliable water level monitoring system for early warning, it will easily lead to major disasters and brin...
