Embodiment 1

[0059] Such as Figure 1-12 , a detection system corresponding to a power monitoring method for a substation, including a server, an inspection terminal, and a plurality of on-site monitoring terminals;

[0060] The on-site monitoring terminal is fixed at each detection point of the transmission line or substation to detect the voltage and current of the monitoring point; the on-site monitoring terminal transmits the sampled current and voltage information to the server;

[0061] There is a data analysis module in the server, which is used to analyze the power quality of the circuit. The power quality includes determining whether the voltage, current and each harmonic (also known as the distortion rate) exceed the preset value;

[0062] The inspection terminal includes an aircraft, and a camera 4 is arranged on the aircraft; the images and videos collected by the aircraft are sent to the server. The aircraft is used to check whether there is any loosening of the monitoring po...

Embodiment 2

[0075] A method for monitoring electric energy in a substation, comprising the following steps:

[0076] Step 1: Data Acquisition

[0077] On-site monitoring terminals set up at each detection point of the substation collect power data;

[0078] The power data includes the instantaneous voltage and current amplitudes collected by voltage transformers and current transformers; the power data can further include the switch state data of each power switch, preferably, detected by sensors, such as detected by angle sensors Whether the switch is in action, or use the camera to take pictures to confirm whether the switch is in action;

[0079] Step 2: Data transfer

[0080] The on-site monitoring terminal transmits the collected power data to the server;

[0081] Step 3: Data Processing and Monitoring

[0082] The server processes the power data and analyzes the voltage amplitude and phase angle, current amplitude and phase angle, power factor, harmonic parameters (including the...

Embodiment 3

[0092] Embodiment 3: The power failure detection system also includes a power failure detection system, including a server and an ice-breaking robot arranged on the power line;

[0093] The ice-breaking robot is equipped with a camera and a remote control signal receiving module; the ice-breaking robot is also equipped with a wireless transmission module;

[0094] The image collected by the camera is uploaded to the server through the wireless transmission module; the server judges whether there is a fault or a potential fault based on the image. If the difference between the diameter of the transmission line and the original diameter exceeds the preset value, it means that there is ice on the transmission line. , there is a potential safety hazard, start deicing.

[0095] The front end of the ice-breaking robot is equipped with an encircling ice-breaking mechanism; the encircling ice-breaking mechanism is composed of two semi-circular components. When the two semi-circular co...

Description

technical field [0001] The invention relates to an electric energy monitoring method for a substation. Background technique [0002] Due to the change of power load and the existence of various short-circuit faults in the power system, the quality of power supply changes, such as voltage drop during peak power consumption, power factor is too small, harmonic component is too large, and current rises significantly when the circuit is faulty. It will affect the stable power supply, so it is necessary to monitor the power quality. [0003] The existing power monitoring generally uses fixed nodes for monitoring, and the monitoring indicators are too small to meet the requirements of all-round monitoring. Therefore, it is necessary to design a new power monitoring method for substations. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an electric energy monitoring method for a substation, which has rich functions and...
