Advanced Distribution System ManagementandEnterprise Engineering & OperationsWayne Carr -- Milsoft
Milsoft – E&O Software Vendor • Founded in 1989 • We Design, Write, Maintain, Sell and Support • Distribution Engineering Analysis • Load Flow, Fault Current, TCC Curve Management, etc… • GIS (ESRI based) • Outage Management • Interactive Voice Response (IVR) • To Over 1000 Utilities and Engineering Firms • With 106 employees in Abilene TX & Pensacola FL & remotely located
Distribution System Management • Wikipedia “A Distribution Management System (DMS) is a collection of applications designed to monitor & control the entire distribution network efficiently and reliably.”
Distribution System Management • We and other vendors have provided applications and collections of apps that allow the utility to monitor & control: • Parts of the distribution network • Part of the time • In some operating conditions • I am not aware that any vendor or utility has implemented a DMS that applies to the ENTIREdistribution network
ENTIRE is defined as: • The ability to monitor and control all conductor, devices and meters: • Overhead and Underground • Transformers, Regulators & Capacitors • Switches and Overcurrent Devices • Meters and Sensors • Customer (end point), Feeder Bay & Line • If you built or installed it, you need to monitor and control it!!
ENTIRE is defined as: • The ability to monitor and direct all crews/vehicles (Work Management) • Where are they now and what are they assigned to do? • How long will they be there? • Do they need additional resources? • What and where are they assigned to be next? • How long will that take? • What resources do they have • Do they need additional resources?
ENTIRE is defined as: • All the time under all conditions: • Normal operating • Emergency • Terrorist attack, Cyber attack, Traffic attack • Outage situations • Normal and Storm • Outage prediction • Public and Employee Safety situations • Line down, etc… • Community notifications • Coordination with Police and Fire
How does ADMS task? • ADMS needs to work with (task) utility the way the utility wants it to work: • System Monitoring • What is the status of devices • Switching closed/open, Capacitor on/off, Regulation taps • What is the voltage and current flows at all points • Who has power and who does not have power (OMS) • System Control • Operating switches, voltage control devices & capacitors
Key Component -Real Time Grid Analysis • Real Time Grid Analysis is: • Reading real time metering data • Using real time circuit model data • Defining real time voltages and currents at all points • This becomes data that other apps can use for: • Outage restoration • Low/High voltage alarms • Overload alarms • Regulator and Capacitor control
What does ADMS look like? • ADMS needs to look like what the utility wants it to look like: • What do you want to see and where do you want who to see it? • Control Room • Consoles • Desktops • Laptops and In Vehicle systems • Handhelds (phones, tablets, etc..) • Reporting • Archiving
ADSM – What are the ideal requirements? • Accurate Detailed Circuit Model kept up to date in the real time • Accurate – it must be close to correct • What is there • How it is connected • Detailed • Every installed device with settings • Every foot of installed conductor • Every distribution transformer • Every line sensor & end point meter • As energized now
ADSM – What are the ideal requirements? • Meter and sensor data read and verified in as close to real time as possible • Feeder bay (SCADA) • Line sensors (Voltage and Current) • End Point • Time stamped • Meter data stored and archived • Utility defines point of archival
ADSM Summary • An Advanced Distribution Management System (ADMS) is a collection of applications designed to efficiently and reliably monitor & control everything on your system all the time under all operating conditions
ADMS a System of Applications • Current ADMS applications, like most applications used by our Industry, have a common problem; they are application/vendor centric not data centric: • They own and/or control the data they need • Thus • It is difficult to expand functionality of apps when that expansion requires data from other apps • It is difficult to add new apps that require data from existing apps • Thus problems with integration and interoperability
Data belongs to App and/or Vendors (App/Vendor Centric) • Data in Silos • Data Translation or Import / Export Required Between Applications • Versioning Requires User Intervention • Integration Requires User Intervention • Functions and Apps Require Different Geographic and Analytic Graphics Data • Data Security is Difficult (or impossible)
To Maximize any System of Apps • Data should not be owned by apps or vendors (Data Centric) • Data should be dealt with as its own thing independent of apps • Apps should get data from system and then put processed data back into system
Enterprise E&O -- Data Centric Platform • Data is accessible from an organized data base system (all data on same server system) • All applications use same data base system • Integration is responsibility of vendors not users • Data Security built into data system at lowest possible level • Applications and Functions layer on same graphics data (Open GIS)
Enterprise E&O -- Open Data Environment • Data belongs to Utility (not vendors / apps!) • Utility gives permission to employees, customers and vendors to see, use and/or change. • Data is platform agnostic • SQL, Oracle, Linux, et. Al. • Data is device agnostic (BYOD) • Mainframes, Desktops, laptops, tablets, ephones • Data and applications are naturally mobile; you choose what device and what location to use.
Enterprise E&O -- Open Integration • Integration with existing vendors is responsibility of data platform vendor via: • MultiSpeak • CIM • Custom • Integration with new apps and functions via: • SQL • Oracle • Linux • API (Application Programmers Interface)
Enterprise E&O – Open App Development • Application Programmers Interface (API) used to write and maintain data platform system is published for use by any Vendor and Developer • Utility can choose from applications written by any • Vendor • Employee • University • Government Project
Open GIS Standard (OGS) • Allows development for use of the same Graphics platform (layering) • Used by ESRI and others • Responsibility of platform vendor, not the user
What This Does for ADMS • ADMS applications not limited by what any one vendor or utility can write and/or maintain • ADMS applications are on same graphics and data platform as all other E&O applications • ADMS can be what you need it to be for your utility
Thank you and Questions • A data centric platform approach is theoretical in that vendors such as Milsoft have only begun to do the R&D to make it possible • A data centric platform approach supporting ADMS applications is possible given utility system and software technologies that are available today to our industry
