In power systems, transmission lines and substations are permanently exposed to complex and changing environments, and microclimatic conditions in particular pose serious challenges to grid security. Micro-meteorological phenomena such as strong winds in mountain valleys, ice cover at high altitudes, and salt spray corrosion in coastal areas often differ significantly from large-scale meteorological forecasts:
1, the narrow tube effect wind: the line in the valley area is often due to a sudden increase in wind speed leads to conductor dance, amplitude up to several meters, resulting in a short-circuit between phases.
2, inverse thermosphere ice: alpine mountains at a particular altitude (such as 800 ~ 1200m) is prone to the formation of persistent low-temperature wet fog, conductor ice rate is far more than expected.
3, local thunderstorms: urban heat island or waters around the easy to trigger a small range of strong convective weather, increasing the risk of lightning strikes tripping.
Traditional weather station due to sparse distribution points, data lag, it is difficult to capture the surrounding micro-climate change, and our Shenzhen Dingxin Wisdom Technology Co. "Power Guard Plus"Micro-weather online monitoring device emergence, is a high-precision, intelligent way to meet the power grid on micro-weather real-time perception of the needs of the power grid to provide all-weather, multi-dimensional security guard.
In order to effectively enhance the power grid's ability to withstand natural disasters, many areas have installedMicro-meteorological online monitoring device. The micro-weather online monitoring device supports both automatic and controlled acquisition, and collects data such as wind direction, wind speed, temperature, humidity, rainfall, solar irradiation, and atmospheric pressure at the point where the overhead line towers and substations are located, and works with the fusion algorithms of multiple data sources as well as the communication network backhaul, to help the power grid company realize the digitization of measurements, and to provide data support for the prediction of the weather and meteorological hazards in the future.
The hidden and destructive nature of microclimate requires that the power monitoring technology must be upgraded to refinement and intelligence. "Micro-weather online monitoring device" with the power of science and technology, so that every micro-weather changes are seen, every risk is predicted, and truly realize the power grid from "passive repair" to "active immunization The power grid has truly realized the leap from "passive repair" to "active immunity".
