Converter station valve hall operation environment early warning method based on time series and transverse comparison

Abstract

The invention discloses a converter station valve hall operation environment early warning method based on a time sequence and transverse comparison, and relates to the technical field of DC power transmission, and the method comprises the steps: obtaining historical environment parameters in a valve hall, and enabling the environment parameters to comprise but not to be limited to temperature, humidity, PM2.5 and salt deposit density; constructing a prediction model based on the valve hall environment parameter time sequence; training the prediction model according to the historical environment parameters; collecting environmental parameters in the current valve hall, and sending the environmental parameters to the prediction model to obtain environmental parameters at the next moment; carrying out early warning according to the obtained environmental parameters at the next moment; adopting a plurality of sensors in a converter valve hall to collect temperature and humidity of the valve hall, particles and pollution degree of the surface of a circuit board card. On the basis of online monitoring of the valve hall environment, analysis of monitoring data is performed, the valve hall environment is predicted by adopting a time sequence algorithm, and meanwhile, valve hall environment parameters at multiple positions are compared, so that the hidden danger of stable growth of themonitoring data can be further discovered.

Description

technical field [0001] The invention relates to the technical field of direct current transmission, in particular to a method for early warning of the operating environment of a valve hall of a converter station based on time series and horizontal comparison. Background technique [0002] DC transmission technology has developed rapidly in my country in recent years, and its advantages in long-distance power transmission, cross-regional networking, and flexible dispatching have become increasingly apparent. The converter valve is an important core electrical equipment of the converter station, and its function is to realize rectification and inverter. [0003] As the core component that converts alternating current to direct current, the converter valve has very strict requirements on the operating environment, not only the operating environment temperature and humidity are strictly specified, but also the cleanliness of the entire valve hall is very important for the conver...

AI Technical Summary

Problems solved by technology

[0005] Operation and maintenance personnel entering the valve hall will bring a small amount of dust, which is affected by the airflow and electromagnetic field and distributed in various positions in the valve hall. At present, there is still a lack of effective valve hall environmental monitoring and early warning methods
