Research on Level Monitoring System of Nuclear Power Plant Based on Split Guided Wave Radar

A liquid level measurement system based on HT1200M split guided wave radar is developed to meet the requirements of liquid level monitoring in nuclear power plants. Using guided wave radar technology, the system can realize non-contact liquid level measurement in the harsh environment such as high temperature, high pressure, and strong radiation, and has high measurement accuracy and stability. In order to further improve the system performance, Fast Independent Component Analysis (ICA) algorithm is used to process the data collected by guided wave radar. Fast ICA algorithm is an efficient blind source separation technology, which can quickly and accurately extract the independent components of mixed signals, effectively remove noise and interference, and improve the purity and identification of liquid level signals. After the system is built, the Fast ICA algorithm model is verified by simulation experiments. The experimental results show that compared with the traditional signal processing methods, Fast ICA algorithm has obvious advantages in improving the signal separation speed and enhancing the liquid level signal characteristics. The system shows excellent response ability and measurement accuracy in the simulation scenario of liquid level change in nuclear power plant, and provides a new and efficient solution for liquid level monitoring in nuclear power plant.
