The Case Study subjects are: the design and packaging of a piezoresistive pressure sensor, a capacitively-sensed accelerometer, a quartz piezoelectrically-driven and sensed rate gyroscope, two electrostatically-actuated optical projection displays, two microsystems for the amplification of DNA, and a catalytic sensor for combustible gases.
The industrial RS485/422 serial interface offers all the features of high-performance NI PXI-843x modules plus high-voltage port-to-port isolation.
The real time control strategy and the management method of micro-grid were successfully employed.For example, it is expensive when the distributed power single accesses the grid.The electric power industry has made great progress and development.We adopt labview and its program modules in software and adopt modular instrument system in hardware.Because it is very difficult to enunciate principles of good design' in the abstract, the book is organized around a set of Case Studies that are based on real products, or, where appropriately well-documented products could not be found, on thoroughly published prototype work.The workers can fully grasp the operation condition of the micro-grid and control all the equipments through the monitoring interface.Abstract, this paper describes a micro-grid system and its monitoring system.In order to keep real time, we adopt some measures in software and hardware.The other is super capacitor energy storage system, which can charge and discharge rapidly, so it can help solve some transient problems, which happen when load operates suddenly, or the micro-grid operates from grid mode to island mode.The structure of the monitoring system.The dual mode inverter is indispensable to the microgrid, which is in the lithium battery energy storage system 10-12.When the grid operates normally, it works in grid-connected mode, and the inverter operates in current-control mode as a current-source, controlling the active power and reactive power, so we also call it PQ mode.In this mode, the large grid controls frequency and voltage.First, the program initialization contains setting initial value to the corresponding variables.The monitoring system can start and shutdown the micro-grid system automatically according to a button in the interface.School of Automation Science and Electrical Engineering, Beihang University, Beijing, China.
