摘要： A system and methods for determining points for an algorithm to calculate the frequency of a waveform measured from a monitoring device. Data points are measured from the waveform. A last point of interest from the previous cycle of the waveform is referenced. Four points of interest at equally spaced phase angles from the current cycle of the waveform are determined by calculating the average of the data points around each of the respective equally spaced phase angles of the current cycle of the waveform. The average value of the points of interest in the current cycle is subtracted from the four points of interest and the last point of interest from the previous cycle to compensate for DC bias. A frequency of the waveform is determined based on the determined four points of interest of the current cycle and the last point of interest from the previous cycle. The correction factor for determining sample frequency may be reduced for subsequent cycles in order to increase stability.

摘要： A system and methods for synchronizing quantized sampled data in a monitoring device. A variable frequency output signal is coupled to an analog to digital converter. A fixed frequency clock is coupled to the analog to digital converter. The analog to digital converter samples the output signal at a fixed frequency to produce high speed samples. A group of initial high speed samples is stored from the analog to digital converter over a fixed window of time. The group of initial high speed samples is interpolated to produce a group of fewer low speed samples from the initial group of high speed samples over the fixed window of time. The group of low speed samples is stored as a representation of the variable frequency output signal.

摘要： A method of automatically identifying whether intelligent electronic devices (IEDs) in a power monitoring system are in multiple electrical grids. A controller sends an instruction to each IED in a predetermined time sequence such that each IED receives the instruction at a different time, commanding each IED to begin logging variation data indicative of frequency variations in a current/voltage signal monitored by the IED and to send the variation data to the controller and an associated cycle count of a point in the current/voltage signal. The controller receives the variation data and associated cycle count and determines a peak correlation using a data alignment algorithm on IED pair combinations. If the IEDs are on the same electrical grid, the peak correlations should occur at cycle count offsets that match the order that the IEDs received the instruction. Any discrepancies in the expected order of peak correlations are flagged, and the corresponding IEDs are determined to be on different grids.

摘要： An automated integrated monitoring (IM) algorithm that automatically puts data from a utility monitoring system into context by temporally aligning the data to a common reference point and by identifying the location of each monitoring device in a hierarchy relative to other devices. Frequency variation data is received from all meters. The data is automatically aligned to a common reference point, such as a precise zero crossing, using a cross-correlation algorithm to determine the time delay at which the data is most correlated. Once the data is aligned, power data is received from all meters in a hierarchy, and the monitoring system layout is auto-learned using a correlation algorithm to determine which two meters are most likely correlated with one another based upon their historical power readings. Once the layout is complete, additional decisions regarding hardware and software configuration can automatically be made by the IM algorithm.

摘要： A method of measuring the runout between a gauge and the axis of rotation of a wheel to which the gauge is mounted in each of two orthogonally related planes uses measurements of the angle between the axis of rotation of the wheel and the axis on which two or more angle sensors are pendulously supported at two or more rotational positions of the wheel and measurements of the angle of rotation of the wheel at each of said rotational positions to derive a runout equation which may be subsequently used to compute the runout at every possible rotational position of the wheel.

摘要： An automated hierarchy classification algorithm that searches for a child monitoring device's parent in a utility monitoring system by segmenting the device data measured by a given device pair and calculating a segment correlation coefficient for each data segment. Devices to be placed in the hierarchy are filtered by calculating the variance of their device data and eliminating devices with a low variance. Devices are ranked by computing the sum of squares of their device data and ordering the devices accordingly from highest to lowest. The device data is segmented and segment correlation coefficients are averaged to produce an overall correlation coefficient. Criteria are evaluated to determine whether a device pair is linked. A correlation coefficient is calculated using the complete data series of a device pair, and the solution produced by this approach is compared with the solution produced by segmenting the device data. If the solutions disagree, a likely candidate is determined from a fuzzy logic module.
