Novel Internet of Things Platform for In-Building Power Quality Submetering

Abstract

Abstract:As the number of facilities adopting a Building Management System under the Industry 4.0 paradigm increases, it is critical to ensure the good health of their operations. Business continuity and uninterrupted operations are key requirements for any building, for which Power Quality and Supply Reliability sophisticated monitoring can play an extremely important role. Submetering, as opposed to bulk-metering, implies measuring power consumption for individual units or appliances in a building complex. An Internet of Things mesh network, which brings ubiquitous power quality submetering inside the entire facility, would be extremely beneficial for the management of the building thus ensuring seamless business operations. This work describes a novel low-cost Internet of Things sensor for measuring and analyzing power quality at the input of any individual Alternating Current (AC) appliance, providing an early detection and analysis system which controls those critical variables inside the facility and leads to anticipate faults with early-stage alerts based on on-time data streams treatment. Moreover, the recorded power quality parameters that are processed in the Cloud system can help to reduce energy consumption, as power quality disturbances can be automatically analyzed and even compared to standard values. The proposed Internet of Things sensor will help users to detect most power quality steady-state and events disturbances, while monitoring the energy consumption. This Internet of Things Power Quality sensor is built around a flexible microcontroller, which manages an energy metering Integrated Circuit (IC) through Serial Peripheral Interface (SPI), increasing its original capabilities by including new sophisticated software functionality. Additionally, it wirelessly communicates with a cloud-based Internet of Things Platform to allow the storage and supervision of the different power quality events for the entire facility. An example of the access to the data is also included.

PyFF: A Fog-Based Flexible Architecture for Enabling Privacy-by-Design IoT-Based Communal Smart Environments

“…Similar to submetering [ 42 ] in the electric field, the sensing layer is committed to collecting the greatest amount of data from the environment. It can be best seen as an IoT sub-domain where Internet-connected digital objects sense as many environmental variables as possible.…”

An IoT Based Mobile Augmented Reality Application for Energy Visualization in Buildings Environments

“…The main hardware device is an embedded IoT PQ sensor (see Figure 2). This sensor has been thoroughly described in the work of [15], and it is an owned design that provides information related to PQ and energy consumption about a smart appliance within any facility. Here, the IoT PQ sensor is used to provide information about voltage, current, real power, apparent power, and other important electrical parameters.…”

“…Having information about PQ can be a determining factor in saving energy and increasing system power capacity. Moreover, in the work of [15], compared with the indicated paper, our great contribution is to make possible the "granularity" in the measure of the energy that is offered to the user. So far, the lack of submetering or recording energy consumption "behind the meter", for example, at system-level or into individual appliances, has been an insurmountable barrier that prevented knowing how energy was consumed in detail.…”

“…[17] and enable the aggregation of the whole consumption profiles from the submeters. Submetering networks can be also useful for monitoring energy quality, not only for analyzing the power consumption [18].…”
