Enhanced substation modelling

Enhanced substation modelling module

Features

The substations modelled appear as icons on the overall representation of the circuit to avoid cluttering the view. A click on any one of those nested views reveals the content in a separate, editable schematic view.

The substations can be modelled in detail using the extensive CYME software equipment library (buses, cables, transformers, switches, circuit breakers, protection devices, etc.). The user can also create new components, based on the detailed templates of the library, to allow the right match with the nameplate data of your particular equipment. Once installed on the system model, the component settings can be adjusted as required.

Eaton's CYME software uses the data of the complete connected model in its calculations.

Enhanced analysis results

The ability to add modelling detail upstream of distribution feeders provides the capability to indicate the dependency between the feeders connected to the same substation bus bar. This valuable data translates into the more precise simulation of the distribution system. 

• Fault analysis – the ability to simulate the effects of one circuit fault on the other circuits connected to the same bus bar. This includes:
  • Voltage drop
  • Fault contribution (if DG or DER is present on the network)

• Load allocation – the ability to compute the substation transformer and/or voltage regulator diversity factor

• DER impact evaluation  
  • The ability, through a load flow simulation, to identify reverse power flow from one feeder to another or even to the transmission/sub-transmission system

• Contingency analysis  
  • Simplifies contingency analysis by allowing the user to easily simulate an out-of-service substation transformer (and thus all feeders connected to this transformer)

Sub-network modelling

More accurate simulation results lead to the more precise planning and management of the expansion and maintenance of the distribution system and a greater facility to manage the integration of the distributed generation (DG) and distributed energy resources (DER) in the power grid, saving time and money.

The Sub-Networks Modelling module is included with any of the other CYME circuit/system modelling modules and shares similar features. It supports the creation of any sub-network, including utility vaults, switching cabinets and modular substations, DG and DER components in a nested representation connected to the overall grid.

The user can create a sub-network in a schematic or georeferenced view style as needed. Each can be shown as clickable, nested-view icons on the overall main representation of the system, revealing the editable view of the sub-network.
