this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...

This paper presents 200 KW three phase standalone photovoltaic systems supplying pumping station consist of four pumps 40 KW rating. The system utilizes a two stage energy conversion power conditioning unit topology composed of a DC-DC boost converter and three level-three phase voltage source inverter (VSI). The Boost converter in this paper is designed to operate in continuous mode and contro...

This paper presents a new Unified PowerQuality Conditioning System (MCUPQC),capable of simultaneous compensation for voltage and current in multi-bus/multi-feeder systems. By using one shunt Voltage-Source Converter(VSC) and two or more series VSCs the configuration is made. The system can be applied to adjacent feeders to compensate for supplyvoltage and load current imperfections on the main ...

Aiming at solving the problems of high compressor discharge temperature, pressure, insufficient cooling capacity, and reduced system efficiency in air-conditioning pure electric passenger cars summer temperature environment, this paper develops a low pressure economizer using principle quasi-two-stage compression cycle. The heat pump air conditioning air-supplemented car is set up to study its ...

Despite the widespread distribution of inhibitory synapses throughout the central nervous system, plasticity of inhibitory synapses related to associative learning has never been reported. In the cerebellum, the neural correlate of fear memory is provided by a long-term potentiation (LTP) of the excitatory synapse between the parallel fibers (PFs) and the Purkinje cell (PC). In this article, we...
