Injection of wind power into an electric grid affects the power quality and reactive power issues at the connected electric network. Power quality problems such as voltage sag are some major concern. In this paper these issues are analyzed. Wind turbine connected to squirrel cage induction generator is modeled using PSCAD simulation software to analyze the said issues where STATCOM is introduce...

This paper aimed to introduce a real-time reactive power controller based on artificial neural network. A feedforward employing back-propagation was used as training algorithm. The inputs to the ANN were real and reactive power of each load. The targets were to switch ON/OFF the capacitors during normal and abnormal conditions. The network was trained and the weights corresponded to minimum (MS...

The reactive system concepts are an attractive paradigm for system design, development and maintenance because it separates policies from mechanisms, which has a particular significance in fault-tolerant computing. The paper presents the design and implementation of reactive systems based on the Actor model. Three generic actor classes: DMMs, Sensors and Actuators are designed and implemented a...

We define a reactive semantics for a subset of UML activities that is suitable as precise design language for reactive software systems. These semantics identify run-to-completion steps for execution on the level of UML activities as so-called activity steps. We show that activities adhering to these semantics and a set of rules lead to event-driven and bounded specifications that can be implem...

reactive oxygen species (ros)plays an important role in sperm motility. the physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

Current co-design methodologies of control dominated hardware software systems su er from ine cient hardware (HW) and software (SW) synthesis of the various reactive system tasks. In order to improve synthesis quality, we propose a methodology that incorporates data ow in addition to control optimizations performed on a suitable task representation in a hardware and software co-design environme...

Reactive languages such as Esterel, Lustre, Signal , Statecharts etc have found wide use in the development of veriiable software for reactive applications. It has been recently argued that both asynchrony and perfect synchrony are needed for the speciication of complex reactive systems and a paradigm called Communicating Reactive Processes has been proposed for such a uniication. The paradigm ...

Many systems developed in Philips Research, especially those that serve as demonstrators for research ideas or product proposals developed in the Lifestyle sector, are so-called reactive systems. A reactive system consists of sensors, actuators and a control module. Sensors and actuators are usually realized in hardware while the control module is usually realized in software. The control modul...

The current demands for seamless connections with the surrounding environment make software more reactive. For example, such demands are evident in systems consisting of the Internet of Things. Such systems include a set of reactive values that are periodically updated in response to external or internal events to form a dataflow in the sense that such updates are propagated to other reactive v...
