1.A new approach is proposed to choose wide area feedback signals for wide area damping controller (WADC) in bulk power systems. Firstly, a novel signal selection benchmark is proposed, which is related to modulation amplitude of WADC and reflects the real control cost.
2.Abstract: The paper introduced the theory of piping transportation of the 1 500 deadweight ton bulk cement barge, and provided the numeration and selection method of main parameters,such as pipe diameter,wind pressure,flux,etc.
4.A rapid method to determine the total ginsenoside in Panax notoginseng for the genotype selection has been established in this study through the investigation of the best treatments covering sample weight, ultrasonic time, granularity, ultrasonic power, reagent, reagent bulk.
