Abstract

The invention discloses a LabVIEW-based household monitoring system of wind-solar-diesel hybrid power generation. The monitoring system is composed of a hardware part and a software part. The hardwarepart consists of a wind-solar-diesel hybrid power generation system, a sensor module, a signal conditioning module, a data acquisition card, and a PC machine. The software part that is developed based on a LabVIEW platform and is used for displaying monitoring data consists of a photovoltaic cell panel monitoring module, wind power monitoring module, a storage battery monitoring module, an inverter monitoring module and a diesel generator monitoring module. According to the monitoring system, the sensor module is used for sending various collected analog signals of a wind-solar-diesel hybridpower generation system to the signal conditioning module to carry out differential amplification, filtering, and then outputting; the data acquisition card carries out analog-digital conversion and is connected to the PC machine through a PCI bus to carry out displaying. The system can be installed conveniently; measurement is done accurately; the extensibility is high; various data of the wind-solar-diesel hybrid power generation system can be collected in real time; and the data information can be displayed and stored.

Description

technical field [0001] The invention belongs to the field of power generation system monitoring, and in particular relates to a household monitoring system for wind and diesel complementary power generation based on LabVIEW. Background technique [0002] With the rapid development of the economy and the increasing demand for electricity, distributed energy, as a new type of energy, has received more and more attention. Among them, the household solar-diesel hybrid power generation system is a distributed power generation system established by making full use of the complementary advantages of solar power generation, wind power generation and diesel power generation. Compared with a single wind power generation system, photovoltaic power generation system or diesel power generation system, The wind-solar-diesel hybrid power generation system has low cost, low pollution, can effectively solve the discontinuous problem of single power generation, and improves the reliability of ...
