Ipsa 2 Advanced Workshops

The Advanced Workshops are a series of one day hands on training courses for the power system engineers who would like to further their analysis capabilities using the more specialised analysis modules in Ipsa. Delegates will use the advanced Ipsa analysis functions to perform transient stability simulations and harmonic analysis, as well as gaining an insight into protection modelling and grading. Courses are normally held at our Manchester offices. We will provide computers for the duration of the training course. Delegates may use their own computers but please ensure that the latest version of Ipsa 2 is installed prior to the start of the course. We can provide temporary Ipsa licenses if required.   Our next 3 day Advanced Course will run from the 3rd - 9th May 2018.   The Advanced course covers:  
  • Protection (3rd May)
  • Harmonics (4th May)
  • Transient stability (8th May)
  • Python programming (9th May)
  It is recommended that the Introductory Ipsa Training Course is completed before attending one of the workshops. Each workshop includes a presentation of the relevant theory followed by the Ipsa modelling aspects. Hands-on examples are used to demonstrate the different analysis features and relevant power system phenomena. Each workshop takes place over a full day and delegates are free to choose which workshops they attend. The workshop agendas are outlined below;  
  • Transient and Dynamic Analysis (one day)
    • Modelling aspects including governors and AVRs
    • UDM models
    • Plugin Models
    • Motor starting
    • Generator critical clearing time studies
    • Transformer Inrush
  • Harmonic Analysis (one day)
    • Modelling aspects including harmonic sources and background representation
    • Impedance scans
    • Harmonic voltage studies
    • G5/4 compliance
  • Protection Modelling and Reliability Analysis (one day)
    • An introduction to the Protection Device Modelling tool
    • Protection Grading studies
    • Protection Grading studies
    • An Introduction to distribution reliability studies
    • Reliability modelling and analysis
  • Python Scripting (one day)
    • An introduction to the Python scripting
    • Data types
    • Control flow
    • Interfacing to Ipsa
    • Automating Ipsa studies
  Questions and answers on advanced modelling techniques / issues;   Fault level analysis - involves applying short circuits at various points on the network and calculating the resulting current flows. The results from fault analysis can be used to evaluate abnormal operating conditions, power systems design, switchgear selection, estimating appropriate relay settings, and the design of network earthing systems. This training module includes introduction to fault level theory and fault level calculations in Ipsa. This includes initial fault analysis, data requirements, running fault analysis calculations, waveform plots and Ipsa based examples. Transient stability analysis - determines if a system is able to return to a stable condition following a system disturbance, such as a fault on the network. This training module includes an introduction to basic transient analysis theory (Equal Area Criterion), modelling Automatic Voltage Regulators (AVR), examples of transient response of synchronous machines and Induction motor models, transient stability in multi machine systems, applying faults and plotting results in Ipsa. By the end of this course the attendees will be able to successful run a transient stability calculation in Ipsa and analyse the results. Harmonic analysis- predicts the harmonic distortion impact of power electronics and other harmonic sources on the AC network. This module will enable the attendees to become familiar with the fundamental theory on harmonics and harmonic device modelling in Ipsa, run harmonic calculations, harmonic impedance scans, producing impedance and voltage waveforms, and harmonic penetration calculations in Ipsa. The Protection Device Modeler (PDM) - designed to create, view and modify protection devices such as relays, fuses and damage curves. This module includes modelling of protective devices in Ipsa, adding protection devices to a network, adding and editing items, creating items characteristics and Ipsa calculating grading curves. This is a half-day Advanced Ipsa Workshop which is run in conjunction with the Reliability course. Reliability - provides an introduction to Distribution system reliability modelling and analysis. The concept of protection and restoration zones are presented alongside the Ipsa modelling requirements. Analysis examples are provided which illustrate the calculation of common UK and US reliability indices such as Customer Minutes Lost (CML etc) and System Average Interruption Duration Index (SAIDI etc.) Python Scripting - allows users to benefit from the power of automating Ipsa courses are available to introduce the Python scripting language and its use in conjunction with Ipsa. Attendees will learn Python basics, how to automate Ipsa studies, change data, transfer results to Excel.   Copies of training examples used during the presentations will be distributed prior to the start of the course. Lunches and refreshments are included. If you would like more information then please contact us
