| 在变电站运维局部放电监测中，超声波传感器的测量结果会受到电场、磁场、环境湿度、温度及振动物理场及其耦合作用影响，导致测量可靠性下降甚至信号失真。因此，针对超声波传感器的多物理场耦合影响量化问题，构建多物理场耦合传感器测试平台，模拟实际变电站复杂场景，开展单物理场及二、三、四、五物理场耦合下的超声波传感器测量影响实验研究。实验结果表明，仅施加单物理场时，振动使超声波传感器测量值严重失真，最大误差达69%，在不施加振动的情况下，温度和湿度对传感器的影响较大，最大相对误差均达到9.4%；在二、三、四、五物理场耦合下，振动与其他物理场耦合时的传感器误差高达60.3%，在不施加振动的情况下，超声波传感器测量值变化趋势主要受温度影响。根据实验结果得到传感器多物理场耦合影响模型，揭示了多物理场耦合对超声波传感器测量值的影响规律，为超声波传感器的测量误差校准提供依据。 |

| In the partial discharge monitoring of substation operation and maintenance, the measurement results of ultrasonic sensors are affected by the electric field, magnetic field, environmental humidity, temperature, and vibration, as well as their coupling effects, leading to a decrease in measurement reliability and even signal distortion. Therefore, in order to quantify the influence of multi-physical field coupling of ultrasonic sensors, this paper constructs a sensor test platform with multi-physical field coupling, simulates the complex scene of actual substation, and carries out experimental research on the influence of ultrasonic sensor measurement under single physical field and two, three, four and five physical field coupling. The experimental results show that when only a single physical field is applied, the vibration makes the measured value seriously distorted, and the maximum error is 69%. Without vibration, temperature and humidity have a significant impact on the sensor, and the maximum relative error is 9.4%. Under the coupling of the second, third, fourth and fifth physical fields, the sensor error is as high as 60.3% when the vibration is coupled with other physical fields. Without applying vibration, the change trend of the measured value of the ultrasonic sensor is mainly affected by temperature. Based on the experimental results, a multi physics field coupling influence model of the sensor was obtained, revealing the influence law of multi physics field coupling on the measurement values of ultrasonic sensors, and providing a basis for error calibration of ultrasonic sensors. |
