Diverse Data Collection

The DME data collection process includes periodic polling for the latest:

• Fault records (FR)
• Sequence of events records (SER)
• Disturbance records (DDR)
• Maintenance records (MR) (such as communications, settings, clock, commissioning)
• Real time load data
• Real time temperature data

Features

Wavepoll has the ability to:

• Poll up to 2000 devices simultaneously (periodically or upon demand).
• Support RS232, RS485, Modem (ASCII, Binary), and Ethernet communications.
• Support communication protocols include TCP/IP, FTP, SFTP, Telnet, IEC61850 MMS, as well as a multitude of proprietary protocols.
• Support both star and multi-drop network topologies and reports periodically or by exception.
• Provide health checks including communications integrity, access logs, and polling errors.
• Provide terminal interfaces with programmable function keys and escape sequences.
• Import/Export spreadsheets (CSV files) for rapid configuration development and maintenance.
• And More...

Tools

Wavepoll can be used to:

• Create and maintain multiple device configurations.
• Duplicate option for fast configuration.
• Export configurations to CSV format.
• Import configurations from CSV formats.
• Archive and manage access and polling logs.
• Query and sort engines for user logs.
• Access devices with ASCII and Binary Terminals.
• And More...

Line Groups

The process of preparing DME data for analysis is time consuming. The process includes selection, conversion, validation, alignment, calculation and merging of analog and digital data channels. The purpose for Line Groups is to automate the process of preparing data by using templates and scripts as defined below. The successful use of Line Groups results in significant reductions in the time it takes to prepare data for analysis (from minutes to seconds), and enables automatic analysis and report generation features which include health checks and fault location reports.

A Line Group is a set of fields that identify the analog and digital channels of a specific line in a specific DME such as a Digital Fault Recorder (DFR), or a Sequence of Events Recorder (SOE) or a digital relay. The fields are used for identifying the line’s three phase currents and voltages and associated events, and other related information such as line length, impedance, and remote end identification.

Built-in Script Commands

All the values needed for automation are defined by our custom script commands. The commands provide measurements of prefault and fault vectors for both voltage and current phases. They also include impedance and length values needed for running the single and double ended fault location algorithms as well as calculating unbalances, channels with polarity issues and pegged channels.

Data Centralization

Data files inserted into the database include but not limited to:

• Oscillography/event key parameters
• DME alarm and configuration/settings
• Syncbackpro logs
• DAU logs
• Wavewin SER data
• Health checks
• Transformer temperatures
• Relay settings

Advanced Analytics

The Wavebase software contains the following advanced analytics:

• Double-Ended Fault location
• 3-Phase Fault location
• Multi-Phase Fault Location
• Reactance Fault Location
• Radial Fault Location
• Classify events as Single-Ended Fault, Double-Ended Fault, Thru Fault, or a Non-Fault (Possible Mis-Operation)
• Fault Type and Fault Summaries
• Negative and Positive Sequence
• DME configuration/setting changes
• Analog Verification (Imbalance, Pegged Channels and Channels with Polarity Issues)

Web BI Server

3Wave has the ability to work with most of the Web BI software on the market today, allowing it to create user friendly informative DME reports and dashboards in multiple environments. 3Wave also allows users to set up weekly, monthly, and yearly reports. Some example reports and dashboards are listed below.
