9. A method for adapting a real-time monitoring system of an electrical power engineering according to claims 1-8, comprising:
s1, sensor installation: installing sensors according to the parameters of the power system to be monitored so as to acquire the voltage, current and power parameters of each node of the power system;
s2, data acquisition: the data acquisition module is used for acquiring and processing the data acquired by the sensor, converting the data into digital signals, and storing and marking the digital signals;
s3, data transmission: the communication module is used for transmitting the acquired data to the monitoring system, and the data transmission can be performed through a wired or wireless network, so that the real-time performance and the reliability of the data are ensured;
s4, data processing: and processing and analyzing the data acquired by the sensor by using a data processing module. Parameters of the power system can be calculated and analyzed to obtain a real-time state of the power system;
s5, alarming and controlling: the operation state of the power system is monitored by using the monitoring control module, alarming and control operation are carried out according to a preset threshold value, and when the power system is abnormal or exceeds a specified range, the system automatically gives out an alarm and triggers corresponding control operation to protect the safe operation of the power system;
s6, visual display: the visual interface module is used for displaying the monitored data to a user so that the user can intuitively know the running state of the power system, and the user can check the change condition of each parameter of the power system in real time through the interface;
s7, data analysis and report: the data analysis and reporting module is used for analyzing the collected data and generating reports so that a user can evaluate the performance and diagnose faults of the power system, and the reports can provide basis for decision support and fault investigation for the user.
