Power plant management relies on monitoring many signals that represent the technical parameters of the real plant. The use of neural networks (NN) is a novel approach that can help to produce decisions when integrated in a more general system. In this paper we introduce a NN module using an ART-MAP to discriminate different situations from the plant in order to prevent future malfunctions. A s...

The article discusses application of AC/DC/AC converter cooperating with an induction generator in small hydroelectric power plants. The induction generator works with power grid or a separated group of receivers, enabling to generate power even at low speeds of the turbine. The article provides also results of the investigation concerning the functioning of the generator coupled with AC/DC/AC ...

We analyze the speciication of a hydroelectric power plant by ENEL (the Italian Electric Company). Our goal is to show that for the speciication of the plant (its control system in particular) some given properties hold. We were provided with an informal speciication of the plant. From such informal speciication we wrote a formal speciication using the CCS/Meije process algebra formalism. We de...

Abstract. In this paper, we value hydroelectric power plant cash flows under a stochastic control framework, taking into consideration the implication of operational constraints such as ramping and minimum flow rate constraints for the purpose of environmental protection. The power plant valuation problem under a ramping constraint is characterized as a bounded stochastic control problem, resul...

A new micro-optical vibration sensor has been achieved by combining “integrated optics” and “micromachining” on silicon technologies. The high sensitivity and the wide frequency range have been obtained by using a multimode section in the optical detection circuit. Three prototypes have been installed successfully in an industrial hydroelectric power plant.

The paper presents a software agents society, which implements a more efficient control and monitoring system for a complex heterogeneous system – multiple hydroelectric power plants connected in a chain on Somes River. The agent society can be superimposed over the existing SCADA control and monitoring network and aims to increase performance, efficiency and stability in the existing monitorin...

The mathematic representation of the tailrace elevation as function of the water release can be modified, for example, by the geomorphologic impact of large floods. The level-release polynomial from a hydroelectric plant is important information to computational models used for optimization and simulation of the power generation systems operation. They depend on data quality to provide reliable...
