Gaining New Engineering Perspective
Software shouldn’t have a steep learning-curve any more. Engineering students have all more-less been taught the basic way to solve a problem. Once we leave college, why do experienced individuals use software with completely new learning paradyms? 1. Moving the data from one source into the analysis software is not possible. 2. Characterizing data is a manual process. 3. Software doesn’t use the process that is used in college. 4. Academics have not synchronized the classroom teaching with their research process. Research solves a a problem in the most expedient way, it does not optimize the ways to learn about it.
What is the big goal?
The big goal is to create models that mimic what’s used in college. Many times the model is just a source, impedance, load model. This is the simplified form of much work of combining many impedances.
Substations:
Wire sizing for transients
Wire must be sized to take transients to ground while keeping eliminating unsafe potentials. These wires are connected to any steel/metal within a substation. Potential is short for potential difference or voltage. Equipment and people must be protected from unintended circuits created by random injected energy such as lightning or broken equipment/conductors that fault.
Wire models can be either high- or low- frequency. External energy, energy stored in an electromagnetic field, or mechanical devices cause the high frequency or overcurrent transients. Low frequency models are employed as steady state with subsynchronous multipliers.
Model Standardization
Modeling software is typically created on it’s own island. You must create your models from scratch unless you hire a consultant to create a tool to move data into it. Ubiquitous models would be incredibily helpful. Fortunately, the container has already been created. It is called a Functional Mock-up Interface specification. Over 150 software tools can use the specification’s Functional Mock-up Unit (FMU) within their models. Unfortunately, Spice does not support FMU’s.
