摘要： Systems and methods are provided for estimating power breakdowns for a set of one or more appliances inside a building by exploiting a small number of power meters and data indicative of binary power states of individual appliances of such set. In one aspect, a breakdown estimation problem is solved within a tree configuration, and utilizing a single power meter and data indicative of binary power states of a plurality of appliances. Based at least in part on such solution, an estimation quality metric is derived. In another aspect, such metric can be exploited in a methodology for optimally placing additional power meters to increase the estimation certainty for individual appliances to a desired or intended level. Estimated power breakdown and energy breakdown—individually or collectively referred to as consumption breakdown—rely on measurements and numerical simulations, and can be evaluated in exemplary electrical network utilizing binary sensors.

摘要： Time synchronization of two clocks is disclosed herein, such as two stationary clocks. A global time signal from a global time reference or common time source can be used to calculate a common view based clock offset between the two clocks. In parallel, a network based clock offset between the two clocks can be calculated based on messages exchanged over a communication network interconnecting the two clocks, without reverting to the global time reference. Two recent values (e.g., the two most recent values) of the common view clock offset and the network based clock offset can be combined or superposed in a seamless way to produce a final time offset estimate. The combination of independently calculated common view and network based clock offsets can be a weighted average of the two values, involving respective weights based on quality estimates of the latter. The time synchronization schemes based on a Global Positioning System (GPS) and a wide area communication network can be combined to synchronize the stationary clocks of phasor measurement units (PMUs) of a wide area monitoring system to a central server clock at a Network Control Center (NCC) of the system.

摘要： The power and environmental condition monitoring system monitors the quality of power provided to a site as well as other environmental conditions that might affect the operation of electronic equipment at the site. The system detects and records power events, such as spikes, sags, surges, and other transients, records power conditions, such as voltage level, RMS volts, phase differential, A/C frequency, current, and impedance, and records environmental conditions, such as temperature, vibration, and humidity. The system includes an analog signal receiver that receives analog signals from measurement devices and converts the analog signals into digital signal data. At least some of the channels on the analog boards are high frequency channels capable of receiving and converting high frequency voltage event signals. The system also includes a digital signal processor (DSP) for reading the raw digital signal data from the analog signal receiver and for processing the raw digital signal data. The DSP processes the digital signal data by logging low frequency digital data and by detecting and logging high frequency event digital data. The high frequency event digital data is detected by classifying the data and analyzing the data based upon the class with as few data points as is needed.
