Exploration on Load Signatures

چکیده
Knowledge of electric load signatures is the foundation of practical technologies for load monitoring, which involves the identification of an electric appliance and the determination of its operating state. Such knowledge can provide benefits to utilities, customers, appliance manufacturers and other stakeholders. Many approaches can help to understand the load characteristics of electrical appliances and equipment. This research focuses on the two core components of these approaches: (1) methods to measure and represent load characteristics, and (2) the development of signal processing techniques and estimation algorithms for signal filtering, signal disaggregation and load recognition. This paper presents the methodology and observations of the load signatures in their operation modes. The current and voltage of typical appliances are measured, and characteristics of the waveform signatures so obtained are analyzed. By studying the collected data, it is planned to develop an algorithm that can provide a basis of a taxonomy of electrical loads and an archive for stakeholders’ reference.

Investigation of blind massive sulphide deposit signatures in the calcrete layers as a geochemical barrier: A case study of Areachap, Kantienpan and Copperton deposits
The trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. A very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. These elements may be concentrated in non-magnetic and magnetic part of calcrete. Based on the current research, mineralogica...
متن کاملLoad Signature Formulation for Non-Intrusive Load Monitoring Based on Current Measurements
In this paper we present a new methodology for the formulation of efficient load signatures towards the implementation of a near-real time Non-Intrusive Load Monitoring (NILM) approach. The purpose of this work relies on defining representative current values regarding the 1st, 3rd and 5th harmonic orders to be utilized in the load signatures formulation. A measurement setup has been developed ...

متن کاملAn efficient and inexpensive method for activity recognition within a smart home based on load signatures of appliances
With the increasing demand in terms of non-intrusive appliance load monitoring (NIALM), more and more smart meters and smart analyzers were released on the market to extract well-defined load signatures and/or for performing autonomously the various monitoring operations as needed. Nevertheless, this hardware proves to be very expensive and not necessarily accessible to all. Moreover, most appl...
متن کاملPersonality, space use and tick load in an introduced population of Siberian chipmunks Tamias sibiricus.
1. Although behaviours can contribute to the heterogeneity in parasite load among hosts, links between consistent individual differences in behaviour and parasitic infection have received little attention. We investigated the role of host activity and exploration on hard tick infestations of marked individuals in a population of Siberian chipmunks Tamias sibiricus introduced in a suburban Frenc...
