AE testing is one of the most effective means to detected battery performance, and routine maintenance and testing work has a very important significance. Through domestic and international testing standards, and combined with the actual needs of the scene, a practical capacity storage battery string field test method has been concluded. The current test method has been used in the field, and the...
In this paper, we analyze the mutual relationship among parameters in the anti-surge controlling process of centrifugal air compressor; build time-varying system of air compressor for anti-surge; put forward generalized predictive control method based on cascade control; and apply to the governing system which separates the deep and cold air for a certain chemical plant. The results showed that this...
The constant pressure controlling progress of air compressor, limited by the production load and the changing of compression material flow, directly influences the condensation and separation, purification and rectification of the air, and the energy consumption of the system, is a representative time-varying system. In this paper, the coupling correlations among many parameters during the constant...
Ultraviolet (UV) imaging is an effective visual discharge detection method. In this paper, the ceramic insulator pollution discharge character was researched with the UV imager in the artificial climate chamber. According to the discharge UV image, the discharge type is divided into two typical forms, one is corona discharge, and another is the partial arc discharge. Using digital image processing...
Optical radiation is a very important character signal of high-voltage equipments surface discharge, and it can be used to characterize the equipment insulation condition, but usually, the equipment surface discharge is very weak, and the light signal mainly distributes below 400 nm ultraviolet (UV) band. To detect the solar-blind band UV signal, it can not only help us to find the early discharge,...
Real-time prediction of video source traffic is an important step in wireless network management tasks such as dynamic bandwidth allocation and end-to-end quality-of-service (QoS) control strategies. However, together with the slowly-decaying auto-covariance function (ACF) and the traffic non-stationarity, it suggests that some conventional prediction tools, which only use short-range dependence (SRD)...
