Embodiment Construction

[0082] figure 1 is an exemplary implementation of an energy management system 100 according to the present application.

[0083] The primary source of information flow for the home is shown as a smart meter 102 , which acts as an authentication center, coordinator and / or energy service portal (ESP), and which is configured to communicate with a home energy gateway (HEG) 104 .

[0084]It is well known that these functions of the smart meter 102 can be separated into different devices. For example, if the residence does not have a smart meter 102 (so the electricity meter only functions as a meter to provide consumption information), other components may be used to provide additional capabilities. For example, a residence without a smart meter 102 could have the metering functionality of the smart meter 102 replaced with a simple radio and CT configuration. Also, there are devices that can be placed outside the meter to communicate its consumption by reading the meter's pulse ...

Abstract

The present invention relates to diagnostics using auxiliary metering devices. Systems and methods for diagnosing a device, such as an appliance (702), using a secondary meter device (704) that measures electrical characteristics related to usage of the appliance within a HEM network (700) and provides such data to a residential energy controller (706) or the like. The auxiliary instrumentation device may include one or more sensors (724), such as current transformers, Rogowski coils, shunt resistors, or Hall effect sensors, etc., for collecting data related to active power consumption, reactive power consumption, line frequency, line voltage, etc. , power factor, lead / lag voltage-current comparison, and apparent power.

Description

[0001] related application [0002] This application claims priority to US Provisional Application Serial No. 61 / 304,712, filed February 15, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The following disclosure relates to energy management, and more particularly to energy management of household consumer appliances and other energy consuming devices and / or systems present in a dwelling. The present disclosure has particular application to an apparatus that controls the operation of consumer appliances and other energy consuming devices and / or systems and acts as a gateway between a utility company network and these consumer appliances and other energy consuming devices and / or systems . This controller / gateway device to be discussed below is sometimes referred to herein as a Home Energy Gateway (HEG). Background technique [0004] Currently utilities typically charge a flat rate for energy, but due to increasing fuel price costs ...
