New Concept of High-voltage Switchgear On-line Monitoring System
A new concept of a high-voltage switchgear on-line monitoring system (BMS Bay Monitoring System) is described. Main features and benefits of BMS are simple ethernet-based communication which means simple LAN connectivity with other systems in a switchgear, reliable data collection, reliable controller operation, reliable power supply, quick access to data and a quick and simple retrieval of sto...
متن کاملOn-line Voltage Stability Monitoring
This paper presents a new methodology for online voltage stability assessment, consisting of two steps. Firstly, the time evolution of the power system operating state is modeled with the help of a forecasting-aided state estimator; secondly the voltage collapse point is determined through an extrapolation technique based on tangent vector behavior. Tests are carried out using the IEEE-14 bus s...
متن کاملA Coupled Inductor Based High Voltage Gain DC-DC Converter Using Interleaved Voltage Multiplier Cells
In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...
متن کاملResearch on the Error Characteristics of a 110 kV Optical Voltage Transformer under Three Conditions: In the Laboratory, Off-Line in the Field and During On-Line Operation
Optical voltage transformers (OVTs) have been applied in power systems. When performing accuracy performance tests of OVTs large differences exist between the electromagnetic environment and the temperature variation in the laboratory and on-site. Therefore, OVTs may display different error characteristics under different conditions. In this paper, OVT prototypes with typical structures were se...
متن کاملA low-voltage three-axis electromagnetically actuated micromirror for fine alignment among optical devices
In this paper, a new three-axis electromagnetically actuated micromirror structure has been proposed and fabricated. It is electromagnetically actuated at low voltage using an external magnetic field. The main purpose of this work was to obtain a three-axis actuated micromirror in a mechanically robust structure with large static angular and vertical displacement at low actuation voltage for fi...
