I have been involved with the high-medium-low voltage technology over certain periods of my professional - engineering, R&D and scientific - career.
1 Most recently, I have studied various medium-voltage grid connection schemes for the large renewable power systems (Wind and PV, before all). As the size / capacities of the wind parks and PV Farms grows, the actual grid connection voltage also shows tendency toward HV.
2 The renewable power systems growth in generating size has initiated my familiarization with some relevant equipment. GIS/AIS switchgear, relays and control panels, ACDBs, DCDBs, batteries and battery chargers. Protection Standard IEC 61850. Relays ABB, Siemens and GE: feeder, differential, motor and bus bar (REF615, SIPROTEC 5, 7SJ601 , MFAC, Micom). Testing equipment Freja 306, OMICRON CMC 356. Software PowerFactory 2017, DigSILENT for various modeling, simulation & analysis tasks.
3 I have been actively working on generalized approach to various control & automation systems applied within the industry and (renewable) power generation, transmission and distribution. Most recently, I have performed a study of PLC & Process Automation International Standards IEC 61131, ISA-88, -95, & -106, as well as an evaluation of SIEMENS PCS7 Automation Platform – in particular Structured Control Language (SCL) programming language (Siemens' implementation of Structured Text programing standard). My intentions were to unify the interaction with various automation equipment (even from different vendors, not so-well integrated - as Siemens' PCS7 components, for instance).
4 These days there is a lots of comments about the digitalization of various process control domains, including the power transmission systems. My further activities in that direction are directed toward implementation of the tools such as LabVIEW or Matlab/Simulink, with the embedded capabilities of processing the waste amounts of accessible information and thus enabling the actual improvement of the subject processes beyond the basic data collection.
5 In that regards, I have analyzed the actual implementation of IEC 61850 standard's Substation Configuration Language (SCL), since it introduced a comprehensive description of the complete substation's system, supporting/allowing the precise dealings with the single line diagram, function allocations, data (as being mandatory and optional, or extended), services provided and used, connection in the communication system, setting of all configuration & operational parameters (with defaults values) -all defined in IEC 61850- and many other relevant information.
6 I believe the SCL, within the larger frame of IEC 61850, represents another field where modern control tools, if applied, could pave a road toward significant operational, efficiency and every other kind of substation's management improvement. My knowledge of signal processing, real time optimization, and other modern control skills could contribute any professional efforts in the domain of power systems.
7 Another line of my work within the power systems was the design and implementation of various SCADA platforms. For a long time, I have worked closely with Institute Mihajlo Pupin (IMP) Belgrade and, within that cooperation (or individually) I was in a position to work on some large hydro & thermal power plants of Serbia: 'Djerdap' on Danube, 'Bajina Basta' on Drina, 'Nikola Tesla Obrenovac' by Sava. The IMP SCADA was developed around the ATLAS RTU series of microprocessor devices.
8 In Australia, I have developed close professional relationship with Northern Territory's Power and Water Corporation. Formally, I've acted as their Specialist Service Provider: Power-Demand Management Study for Darwin-Katherine Region, Energy Auditing & Management, Grid-Connected Renewable Energy Systems (PV-Solar and Wind), Remote Supervision & Control were our major joint projects.
9 In Serbia, I have worked on various Small Hydro Power Schemes, as an expert for grid-connection, and overall design & installation issues. I'd like to highlight one project: HPP Gruza near Kragujevac. That was a full scale tender-design-construction-installation-commissioning project, where I have acted as an independent contractor, and all the tasks were performed by own business (Sole Trade), and with maximum possible of my personal professional involvement.
10 Recently, I have been honored with an opportunity to give the lecture at the 1903 HPP 'Uzice-Serbia', one among the first alternative current generation facility in the world, following Nikola Tesla /George Westinghouse success at Niagara Falls.
Few more examples of my work with high voltage systems:
- Cooperation within the Electric Impulse (EI) disintegration of materials application - project: conversion of coal into the oil. One million volts – equipment. Novosibirsk / Kemerovo, Russia.
- Work around Nikola Tesla's wireless energy transmission ideas, as a part of my continuous R&D, with Tesla's transformer, among other equipment. Some aspects of Earth / Stratosphere Resonance energy propagation. Equipment voltage: order of magnitude 1million Volts.
- Research around high voltage non conventional measuring transformers, initiated during my student years by then Yugoslavia's largest power equipment company, ENERGOINVEST Sarajevo.
I'd like also to add my experience with various co-generation / three-generation equipment, in particular the ORC-based waste-heat-to-electricity systems.
