Load Flow Contingency

This module is designed to assist in power flow related static contingency analysis. It operates in conjunction with the power flow analysis modules of CYME / CYMDIST 5.02 and higher versions of the program. With it, the power engineer can create contingency events and single- or multiple-outage scenarios, and compare results with the base case network data and connectivity.

The analytical approach used by the Load Flow Contingency module is the same as the power flow modules of CYME / CYMDIST. In other words, the contingency analysis is performed using full AC power flow solutions with no DC approximations. The module features the sequential solution of all contingencies in a single run.

 

 

Load Flow Contingency

 

Analytical Capabilities

The Load Flow Contingency module is structured so that an unlimited number of “what-if” scenarios, without the actual modification of the base case data and connectivity, can be included in a given contingency study. All contingency-related system modifications refer to the base case network. Single outages and/or multiple outages/modifications can be concurrently defined to represent an adverse contingency analysis scenario.

This includes the following:

  • Modify loads globally, individually or by zone
  • Modify generation globally, individually or by zone
  • Connect and disconnect sections
  • Modify shunts
  • Add and remove induction and synchronous motors

Contingency N-1, N-2, N-3

With this option, you can define a group of single-, double-, or triple-section outage contingency studies. The network sections can be selected along with the combination of up to three elements per contingency. The program will create the desired group automatically, including the corresponding studies.

Contingency Ranking

This feature allows you to add or eliminate contingency indexes (ranking) to the tabular report. This contingency ranking methodology is for the automatic ranking, selection of contingency cases and for the identification of the most severe contingencies.

EDS Products Overview

EDS Products Overview

EDS (Elecdes Design Suite) consists of several I&E programs and several utility programs.

The I&E programs are used by instrument and electrical designers for creating diagrams, reports and databases to document their designs. The utility programs are used within EDS for the purposes of learning about EDS and also viewing, editing and printing the designers documents.

Below is a list of these programs. Click on the heading to view a detailed data sheet of each program including a summary features list.
