this paper describes and analyzes a system for controlled aging of electrical Form-Wound Bars and Coils of large rotating synchronous machines. The proposed system allows performing an improved voltage endurance test, if compared to standard procedure given by std IEEE 1043–2002: Recommended Practice for Voltage-Endurance Testing of Form-Wound Bars and Coils [1]. This work will explain the key features...
This work constitutes the second part of a study that aims to analyze the technical and economic implications of the penetration of wind power in the Colombian Interconnected System (SIN).
The theory of central angle is defined in the context of network behavior for dynamic operation. Making reference to cutset angle theory, a methodology for identifying abnormalities on the network is proposed according to central angle evolution. The model is tested on a power system comprising the Colombian electrical network. The performance and robustness of the model is verified with simulations...
Theory of cutset area is defined in the context of network behavior, as much in steady state as in dynamic operation. With reference to cutset angle theory, a proposed methodology for identifying stress on the network is stated for cutset angle evolution. Potential applications for Phase Measurement Units, PMU, are validated on a Colombian network.
The control of mechanical power in wind turbogenerators involves the participation of many subsystems. One of them is related to pitch mechanism, which usually employs conventional PI strategies. This paper presents an alternative for estimating the parameters of this PI controller, using Fuzzy Logic (FL). Matlab-Simulink™ software was used in order to verify the performance of the FL-based parameter...
The goal for solving the expansion planning (EP) problem in electrical systems involves the search for the optimal allocation of output power among available generators to serve the system load in a given time horizon. Currently, environmental aspects and the continuing search for alternative energy sources, push for the integration of wind power generators in the EP problem. In order to fulfill this...
