The RB 211 DLE series staged, pre-mix, lean burn combustor, demands total integration of control system and combustion hardware. The controls design process is described from the conception of the Engine Management System (EMS), which provides protection and control in separate environments, through to implementation of engine development testing. The process of devising an acceptable fuelling strategy to each combustion stage is discussed. This identified the requirements for the computation of complex routines in order to control combustion zone temperatures. The sensitivity of the control design to external conditions of humidity, ambient temperature and fuel composition are explored. Extensive simulation was used to determine necessary instrumentation accuracies. The paper concludes with a review of the development testing and the final control system configuration.

Digital Manufacture

The authors have offered the homeostatic control system architecture for digital manufacture security based on the software-defined network technology. We have highlighted the development features of digital manufacture systems and defined the technology advantages of software- defined networks, which allow these networks to be successfully applied with flexible and adaptive topology for a highly efficient new generation of cyber-physical systems. We have also described the main operating principles of software-defined networks in digital manufacture systems. A description of homeostatic security control technology, which includes a combination of engines to provide stability of the system’s internal environment and structural and functional resistance to external disturbances, is provided. We have proposed and described in detail the homeostatic security control system architecture including three generalized components: monitoring unit, decision-making unit, protection and control unit.

With the development of wireless communication technology and computer technology, more and more smart technologies have been applied in electricity distribution networks. This paper presents an adaptive current differential protection and fast auto-closing system for application in 10 kV distribution networks in China Southern Power Grid. The current differential protection can adaptively change its settings according to the topology change of the primary distribution networks, thus the system effectively reduces the operation and maintenance cost of the power distribution network. In order to restore the power supply for the healthy part of the 10 kV networks quickly after a power system fault is cleared, the protection and control system provides wide area control function for automatic fault isolation and automatic switching. The traditional overcurrent protection and control system have no fault location function, it may take several minutes or even hours to manually locate a fault and then restore the power supply. Compared with the protection and control system of the traditional 10 kV distribution networks, the system developed can locate and isolate faults within 900 ms (assuming that the operating time of the load switch is 700 ms), and can quickly restore power supply in less than one second after a power system fault is cleared.
