Embodiment Construction

[0032] Such as figure 1 As shown, the power system transmission tower online monitoring method of the present invention comprises the following steps:

[0033] (1) Data acquisition step: synchronously collect the four parameters of wind speed, wind direction, transmission tower vibration acceleration, and transmission tower bar strain in the wind field environment of the transmission tower, and obtain the wind speed, wind direction, transmission tower vibration acceleration, and transmission tower vibration acceleration of the wind field environment. Transmission tower member strain data;

[0034] (2) Data transmission step: transmit the data collected in step (1) to the data display module, and store the data in the database simultaneously;

[0035](3) Data display step: display the received data through the display interface through the data display module, and realize the real-time display of the wind speed, wind direction, vibration acceleration of the transmission tower,...

Abstract

The invention discloses an online power transmission tower monitoring method and system of the power system. The monitoring method comprises the steps of data collection, data transmission, data display and analysis and early warning. The monitoring system comprises an onsite data collector, a data transmission module, a database, a data display module and an analysis and early warning module, wherein the onsite data collector synchronously collect four parameters including the wind speed and the wind direction of the wind-field environment of a power transmission tower as well as the vibration acceleration of the power transmission tower and the rod member strain of the power transmission tower, the data transmission module transmits received data to the data display module, the data display module displays the received data via a display interface, and transmits the received data to the analysis and early warning module, and the analysis and early warning compares the wind speed and the wind direction of the wind field environment, the vibration acceleration of the power transmission tower and the rod member strain of the power transmission tower with preset alarm values in the analysis and early warning module, emits alarm signals when the alarm values are exceeded, and thus, prevents the tower from falling off and prevents wires from being broken.

Description

technical field [0001] The invention relates to the fields of actual measurement and data visualization of power system transmission towers, and specifically refers to an online monitoring method and monitoring system for power system transmission towers. Background technique [0002] High-voltage transmission lines are generally located in remote areas such as coastal areas or mountainous areas, and are often hit by hurricanes and typhoons. It is necessary to study the downwind effect of transmission towers in extreme climates. On-site measurement of the wind-induced vibration response of transmission towers and transmission lines is one of the methods to study wind-induced disasters. It can directly obtain the response of the actual structure under wind load, and can truly reflect the atmospheric wind environment and the actual size of the structural system. , to overcome the error between the similarity ratio of the model and the prototype in the wind tunnel test.
