Underground HV Substation Design
27 – 31 MARCH 2017, SINGAPORE
About The Course
HV Substations play an important role in the electric power systems. Specific requirements are set for underground substations which are mainly designed in city centers where land, if available, is sold at a premium and it is often the only feasible way to construct it. The most common underground substation types are for major BSP and distribution substations within the DNO as well as substations supplying underground metros or business and commercial canters.
Properly planned and designed substation is essential for reliable operation of a power system network. A new substation should be built to meet the requirements of the growing load and operation under the changing competitive markets. Upgrading of the existing substations would require a comprehensive knowledge of the substation as well as the overall power system. Specific requirements associated with underground installation are addressed in this course with practical examples of resolving technical challenges such as increase heating due to the electrical load and subsequent losses, planned and unplanned maintenance and provision for quick and effective equipment replacement. Safety requests include explosion and fire hazard, fire escape routes, cable routes describing the mitigating measures and specification for this environment.
This course covers all aspects of medium and high voltage substation design with the particular focus on underground substations including regulatory requirements and general design considerations from feasibility through technical specification and tendering to the detail design. A practical understanding of planning, design, technical specification application and a step by step approach of the underground substation design process is explained as well as design documentation for each design stage.
Health & safety and environmental issues relevant for the underground substation design are covered in this comprehensive course.

Published papers on asset management based on projects and experience in working for distribution companies in Africa and Europe.
Vukan is very experienced in design, procurement, commissioning, erection and refurbishment of major projects in transmission and distribution substations up to 420 kV and hydro and thermal power plants. Served as project manager on several major projects as well as head of the Engineering Group, Vukan was responsible for final design, equipment specifications, layouts tender evaluation and commissioning. He ha s carried out conceptual development of protection and control philosophy for various projects as well as reviewed and approved project drawings and documents. He has applied the latest IEC standards, various codes of practice and engineering recommendations. He has also specific experience in conceptual design of power supply for transportation and traction railway systems, defining the design principles and technical specifications for future design and privatisation process. He has analysed quality of power supply for connection of AC and DC unbalanced load to power network and published papers on practical implementation. Vukan carried out feasibility studies on reactive compensation (SVC and MSC) focusing on voltage variation and harmonic distortion issues.
Vukan has performed technical and economic evaluations, cost benefit net present value analysis, of various transmission and distribution schemes and electrical equipment. He carried out a number of asset evaluation analysis on electrical equipment and published papers on asset management, reliability and maintenance. He has performed equipment assessment and residual life prediction as part of strategic asset management analysis for a major underground transportation company in Asia. His duties have also included equipment arrangement optimisation in particular reliability aspect in terms of failure rate and financial consequences as non-supplied energy to the consumers.
