Description

technical field [0001] The present application relates to the technical field of power system detection, in particular to a power parameter measurement method, system, device, computer equipment and storage medium. Background technique [0002] With the rapid development of the power system, the expansion of the power grid capacity makes the grid structure more complex. To ensure the safe and stable operation of the power grid, the real-time detection and control of the power system is particularly important. The two main electrical quantities of the operating state of electrical equipment, the detection of current and voltage parameters has become the key to the safe and stable operation of the power system. The traditional current and voltage detection technology uses current transformers and voltage transformers to measure the current and voltage in the wires, but the current transformers and voltage transformers are large in size, heavy in weight, require high installati...

Problems solved by technology

[0003] In recent years, with the advancement of sensor chip-related technologies, a method of using a single magnetic field sensor to measure the current of a wire has emerged. However, when using a single magnetic field sensor to measure current, it is necessary to know the spatial position relationship between the sensor and the wire in advance (sensor and wire The spatial distance between), that is, the current of the wire is calculated from the spatial position relationship and the measured magnetic field strength. Therefore, the installation of the magnetic field sensor is difficult. Once installed, the spatial position relationship between the magnetic field sensor and the wire deviates, which will affect The accuracy of the measurement results, and the voltage of the wire cannot be obtained according to a single magnetic field sensor, so the overall measurement of the power parameters cannot be completed
