    Design and implementation of a low cost particulate material transducer
    (Institute of Electrical and Electronics Engineers Inc., 2018) Palo Tejada, Ernesto; Campos Falcon, Victoria; Huanca Cayo, Eber
    This work presents the design, implementation, calibration and test of a transducer system for Particle Material - PM based on the sensor GP2Y1010. This sensor is the principal element of many commercial PM transducers, but its sensitivity for environmental perturbations (such as humidity, temperature, etc.) implies the using of complex instrumentation circuits which increases the final price of this product. In this work is proposed a low cost PM transducer, the main characteristics of its instrumentation circuit are detailed. The characteristics of the proposed transducer such as resolution, precision, range of measurement, temperature operation are near among of the characteristics of commercial transducers. The purpose of this transducer is the monitoring of particle material due to mining activity around the Arequipa city, since the particle material concentration out of permissible range is a potential risk for the public health, in this sense the measurement with a reliable and low cost device is a challenging task. © 2018 IEEE.

    Identification of PV system model for simulation of MPPT controllers
    (Institute of Electrical and Electronics Engineers Inc., 2017) Huanca Cayo, Eber; Palo Tejada, Ernesto; Campos Falcon, Victoria
    The present paper is part of a larger project which aims to monitor and mitigate dust on the PV systems in the city of Arequipa. Its objective is to present a simplified model for simulating PV panels for the design and project maximum power point tracker - MPPT controllers. With an experimental setup, signals of voltage, current, power, irradiance and temperature were acquired. A SEPIC converter that can be controlled electronically was simulated and implemented for using it as variable load. The PV model identified was subject to simulation considering variations of temperature and irradiance. Through these simulation, a MPP voltage set point function was identified. Finally a PI controller was implemented for MPPT system to simulate the identified PV model. © 2017 IEEE.
