Abstract
Description
[Technical Field]
[0001] The present disclosure relates to power grid monitoring, and more particularly to test and measurement systems for power grid monitoring, and more particularly to power vector analyzers (PVAs). [Background technology]
[0002] U.S. patent application Ser. No. 18 / 914,685, filed Oct. 14, 2024 (hereinafter the "'685 patent application," the contents of which are incorporated herein by reference), discloses a power vector analyzer (PVA) device for analyzing and monitoring power on a line.
[0003] Typically, units called phasor measurement units (PMUs) monitor the power grid. PMUs measure the voltage, current, and frequency of the electricity flowing through them. PMUs collect time-synchronized data, which is useful for detecting and identifying grid faults such as blackouts, voltage sags, and other power quality issues. PMUs are installed at various locations within the power grid to provide a comprehensive view of the system's health and enable real-time monitoring and control.
[0004] A PMU typically displays a phasor diagram, which shows the phase angles of the voltage and current vectors for each of the three phases at the location of a three-phase source on the grid. Phasor diagrams, such as 10 in Figure 1, are continually updated as the phase angles change due to reactive loads. Similarly, the voltage and current display on the right shows the voltages of the three different phases as 12, 14, and 16, and the currents of the three different phases as 13, 15, and 17. Area 18 in the current display indicates a transient event. [Prior art documents] [Patent documents]

[0007] However, it is not possible to easily determine the direction of the transient power, the magnitude, the transient apparent power, or how it oscillates between inductive and capacitive reactance at a particular instance. [Means for solving the problem]
[0008] Embodiments as disclosed herein provide a better view and deeper understanding of the characteristics of transient events on the power grid, such as complex dynamic bidirectional apparent power transient events. The origin of these events, referred to herein as transient events, may consist of any of numerous examples, such as a large inductive power start-up, a sudden power injection from a megawatt charging station, a downed power line, an exploding power transformer, or a lightning strike. The present embodiments provide a graphical display that captures all aspects of the dynamic power transient fluctuations in power magnitude, phase angle, and direction over the duration of the transient event.
[0009] The present embodiment normalizes and isolates transient events by incorporating a new tracking limit test circle and defining a tracking null normalization process that removes static power from each PVA and observes the transient event at various GPS locations. This feature allows the system to ignore static power, which changes continuously at a rate slower than that seen in transient events. The static power may be different at various locations on the PVA at various times. The power levels at various monitoring points on the grid may change at various points on the grid at various times, but may not be related to transient events. The embodiment normalizes or nulls out the static power at each normalized location. In this way, each PVA location observing a dynamic transient will observe the transient as it propagates from its source to various other remote locations, causing changes or affecting the PVA. This provides a multifaceted view of the transient event, which can help locate it with the help of an AI vector database of many types of past transient events and known information about these events.
[0010] The present embodiment also creates image and text sequences of the transient event captured from each PVA that captured the event. The embodiment creates a tensor representation of this group of images to obtain a single AI embedding vector for the event data from all PVAs. A language describes the cause, location, or other key characteristics of the event and is associated with the embedding vector for that event. Over time, the vector database grows so the AI system can classify new events occurring on the grid. The vector database can reside in a distribution center, transient substation, control station, or can be distributed throughout the system, automatically updating between sites.

[0012] 2 illustrates an embodiment of a power grid that includes PVAs at strategic locations, which in one embodiment can be identified by GPS coordinates using satellites such as 38. These PVAs may exist in more or fewer locations than those shown. The power grid may include, for example, power generating plants such as 20, transmission pylons such as 22, transmission or distribution substations such as 26, alternative energy generating sites such as wind farms 36, solar farms (not shown), power distribution centers (PDCs) such as 28, and one or more control centers such as 30. PVAs may also exist at power consuming sites, including office or industrial buildings such as 32, single-family homes such as 34, and residential buildings such as 35.
[0013] In an embodiment, the power grid may have a large area with multiple sub-grids, or it may have only one sub-grid. The PDC 28, the control center 30, and all PVAs in the power grid communicate via wireless, wired, or satellite communications. Each PVA may communicate only with the PDC, only with the control center, or among itself. In one embodiment, a vector database 37, shown in FIG. 3, aggregates all information from all PVAs. This can be used to develop derived functions related to grid monitoring and grid enhancement, including, but not limited to, prescribed artificial intelligence (AI) / machine learning (ML) services. AI / ML services may include, but are not limited to, predictive measures such as predictive maintenance, load sharing / peak power distribution, and identifying abnormal trends.
[0014] For reference, an example PVA configuration based on some examples of the present disclosure can be implemented using existing hardware, including an MSO58 oscilloscope (see Non-Patent Document 2) running the Inverter Motor Drive Analysis (IMDA) software package (see Non-Patent Document 4), three TCP0030A high-current probes, and three THDP0100 high-voltage probes, all manufactured by Tektronix, plus additional analysis software. The MSO58 oscilloscope includes a processor and storage memory, which enable it to run, for example, a Windows® operating system and PC application software. Therefore, each PVA may run machine learning software, such as Tektronix's "OptaML," which provides a tensor builder, as described in more detail below (see also Patent Document 4).
[0015] FIG. 3 shows a block diagram of how PVAs and the control center communicate transient events and how the control center can classify transient events. As described with respect to FIG. 2, multiple PVAs (e.g., 24) exist at various locations on the power grid. All PVAs communicate transient event data back to the control center 30. Each PVA may see the same event, providing a unique, multi-dimensional perspective for each PVA location. "Power images," as used herein, refer to images showing transient events communicated by these PVAs. These images include tracking limit test circles, described below, which are useful for identifying the presence and partial magnitude of transient events.
[0016] The tensor builder 33 is responsible for taking apparent power images and metadata from multiple PVAs and integrating them into a single tensor space to create vectors. The process of building tensors is part of the process of building vectors, which involves placing images from the database into videos and integrating the videos into a single vector through the AI embedding model 35 and its transformers. Alternatively, each image and text can be passed through an AI model, such as CLIP (Contrastive Language-Image Pre-training), to create image and text vectors in the vector database 37. While this process creates vectors for each power image from each PVA, multiple vectors for a single event must be combined and compared, for example, by pooling or averaging. The end result is that the AI embedding process, once configured and pre-trained as needed, can continuously add and distinguish new data without the need for retraining, even as grid characteristics change over time. New transient events are formed as tensors, which then become vector embedding representations. This vector is then matched with vectors stored in a database to classify the characteristics of the event. If there is no match, the system notifies the operator, who then provides a classification for the vector to be stored in the database.
[0017] As mentioned above, the vector database may also contain vectors related to monitoring the grid without transient events. The control center may collect information from the PVA periodically or during specific events other than transient events, such as peak power usage or high load events. The ML system may create vectors for these events with solutions such as load balancing or changes in power distribution. If there are conditions during normal operation that require a response, the ML system may provide services to better manage power distribution.
[0018] FIG. 4 shows an embodiment of a PVA. This embodiment of the PVA can display the quiescent power signal on a line in a power grid. FIG. 4 shows a user interface 40 with controls on the left and the user interface 40 on the right. Points 42, 44, and 46 represent the "reference" apparent power signal for each of the three phases on a polar grid, with each phase 120 degrees out of phase with the other two. Lines 48, 50, and 52 and the points on these axes represent zero phase between their voltage and current. Points "above" these lines have inductive reactance, and points "below" these lines have capacitive reactance. Lines 50 and 52 are 120 degrees out of phase with line 48 and represent the phase difference of the power line. The term "reference apparent power" refers to the apparent power displayed before quiescent power removal and is used to distinguish it from apparent power measured after nulling.
[0019] FIG. 5 shows an embodiment of a user interface for the null calculation process, which is described in more detail below. The null process essentially removes quiescent power from apparent power measurements, allowing for more accurate display and measurement of transient power fluctuations. This process may involve using a quadrature synchronous detector (QSD) such as that described in the '685 patent application, which is incorporated by reference in its entirety. A QSD or similar device generates a null vector that "nulls" the quiescent power, displaying only the apparent power. The line 54 between points such as 42 and the center of chart 56 represents the process of determining the null vector; the system adds this null vector to the reference apparent power to remove the quiescent power from future measurements. FIG. 6 shows the resulting display after all three points have been moved to the center 56, indicating that quiescent power has been nulled and that apparent power is now zero on all three phases.
[0020] Figure 6 also shows limit circles 58, which allow the user or control center to set a limit mask, which defines how "far" or how large the apparent power measurement must be from the null center before it triggers a response in the PVA. By applying the null, the quiescent power of each line is "removed" from the display, allowing for better detection of transient events.
[0021] Figure 7 shows the transient apparent power variation relative to the null center, with the transient power shown for each phase, such as 60 for one phase. One or more lines have power levels that exceed the limit mask. When the apparent power transient signal exceeds the limit mask 58, the PVA sends a power image and associated metadata of the transient event to the control center. The user interface displays the message "Transient Detected." Note that the power image sent to the control center is a possible scenario. The control center receives power images from multiple PVAs, which allows for a geographical understanding of transient events, since PVAs in various locations may have different data depending on their location.
[0022] The PVA itself can act as a local node in the AI network, detecting transient events, creating vectors, searching its local copy of the vector database, receiving the transient event classification, and then communicating the classification to other local nodes, including the control center, which can then update their local copies of the vector database.
[0023] The figures described above show events with a "fixed" null. This null does not change with the static power at the PVA's location in the grid. Embodiments of the present application use a "tracking" null to allow the transient event to be separated from the static power. This requires the use of a "tracking" limit circle.
[0024] In the figures above, the limit circles do not track the center of the static power. As mentioned above, users can define limit circles for plotted power signals to identify dynamic transient events. If the system does not track nulls, there will be three limit circles for each power phase, such as tracking limit circle 62 at point 42, as shown in Figure 8. Tracking nulls can be defined separately for each of the three tracking limit circles, which together form a tracking limit mask. The static power for each is the center point of the mask circle.
[0025] Figure 9 shows the display after a small transient event occurs on the power line. In this embodiment, all three phases exceeded the tracking limit mask. The transient event that triggers reporting to the central controller could occur in only one of these phases. The quiescent power in each circle is subtracted from the event total to obtain a power image. In this display, all three limit mask circles move to the center of the vector display. In this case, the power of the transient event is shown as a deviation from the quiescent power, as shown in Figure 10.
[0026] The PVA with tracking null and tracking gate for power grid monitoring according to embodiments of the present disclosure represents a major leap forward in the realm of power grid management and analytics. Embodiments of the present disclosure include a novel approach to grid-wide monitoring of complex, dynamic transient events, using advanced mechanisms such as tracking gate limit test circles and tracking null normalization. Embodiments of the present disclosure capture triggered transient power events from multiple PVAs, observe the events, and submit the data to an AI-embedded system for classification of the event's key characteristics. The innovative design and capabilities of this PVA represent a major advancement in modernizing and enhancing power grid analysis and maintenance.
