A spatiotemporal data model is proposed to represent dynamic road networks based on base State with Amendments model and object-version management theories.
基于基态修正模型以及对象版本管理的思想,提出用于动态道路网络数据管理的时空数据模型。
On the base of traditional vector control, the improving excitation system is established by importing the dynamic change in network voltage and state flux current.
在此基础上,对励磁系统加以改进,将电网电压及等效定子磁场电流的动态变化引入系统,在考虑电网波动情况下建立了风力发电励磁控制系统。
