Reactive power is an essential part of the power compared with active power. It is used to establish and sustain the magnetic field present in electrical equipment possessive of coils, such as transformers and electric machines. The reactive power consumption in large distribution networks can result in a huge reactive power flow, rising line current and a sub-nominal voltage. To avoid these negative...
The problem of urban traffic intelligent control is a key technology of modern urban construction. An improve ChSch model base on cellular automaton is constructed in order to conform to the actual situation of traffic. The simulation results show that big intersection is the main bottleneck and the synchronous and fixed traffic signal makes the road in serious congestion when car flow is large. This...
This paper presents an accelerated life testing method to solve the problem of in-pipe robot reliability in quantitative analysis. By established inverse power law probability density function model based on Weibull distribution, the results of accelerated life testing can be used to extrapolate reliability features of in-pipe robot under the normal condition, especially for single or rare prototype...
