Power System Simulation and Integration Approach<br />
S<strong>of</strong>tware Options<br />
o Siemens Spectrum Power TG DTS (Dispatcher Training Simulation)<br />
Advantages<br />
S<strong>of</strong>tware already installed in our lab<br />
S<strong>of</strong>tware designed to interact with the our system<br />
Disadvantages<br />
Poor documentation<br />
Hard to set up<br />
Technical support period had expired<br />
o DIgSILENT PowerFactory<br />
Advantages<br />
Has OPC communication capabilities<br />
Easy to use<br />
Extensive documentation<br />
Many people in ECpE department use this s<strong>of</strong>tware<br />
Disadvantages<br />
Requires advanced license<br />
S<strong>of</strong>tware Selection<br />
We chose to use DIgSILENT PowerFactory for our power system simulation. It was<br />
becoming apparent that we required technical support from Siemens if we were going to use<br />
Spectrum Power TG DTS. The manuals were not helpful, and they did not contain the<br />
information we needed. This support costs around $20,000 per year—a price clearly out <strong>of</strong> our<br />
budget. We found that there was a graduate student here at ISU doing something very similar<br />
to our project. He was using an OPC server to control breakers in DIgSILENT PowerFactory.<br />
Since this was exactly what we wanted to do, and we knew it could be implemented, we<br />
decided to go with that. The use <strong>of</strong> PowerFactory’s OPC capabilities requires an advanced<br />
license that costs around $2,000. Since this was way less than the Siemens support cost, that<br />
was only going to last a year anyway, we decided it would be better to obtain a license that the<br />
whole department could use.<br />
<strong>Cyber</strong> Attack/<strong>Security</strong> Approach<br />
S<strong>of</strong>tware Options<br />

Advantages<br />
Remote Vulnerability Scanning<br />
Combined the “Document Running Services” and”Document wellknown<br />
s<strong>of</strong>tware vulnerabilities” phases into one scan<br />
Free License available<br />
