|DESS 7||Overview||Why Use DESS|
DESS is a suite of software analysis tools to help you design and run your electrical distribution system more effectively. DESS helps you create an analytical model that behaves in the same way as your real electrical system so you can understand, plan and operate it more effectively. DESS combines economic factors with proven engineering principles so that you can make both technically and economically sound decisions.
DESS has been designed from the ground up for medium voltage distribution systems. It uses algorithms suited to distribution system analysis and the interface is designed to help with the potentially huge amounts of data that may be associated with distribution. It can also address the special conditions such as uncertain loads and the range of X/R ratios that are typically found on distribution systems.
Analysis tools include basics such as load flow analysis and short circuit analysis. They also include optimization and loss reduction tools such as capacitor optimization and feeder configuration.
Why Use DESS
DESS can help you reduce system losses. DESS provides an open point optimization which analyzes your system to help you determine where to place open points so that losses are minimal. You can also use capacitors and phase balancing to reduce losses. The load flow analysis can also help you evaluate choices for conductor sizing and voltage.
Perform What-If Analyses
A key part of the planning process is to compare the effects of different designs. DESS makes it quick and easy to evaluate the effects of decisions such as different conductor sizes, a new feeder, a voltage upgrade, addition of capacitor banks, a load transfer, …, etc. The key to this process is to make it quick and painless to evaluate these options.
Reduce Capital Costs
The value of delaying or reducing capital costs is substantial. For example, if you can eliminate the need for a new substation, or even defer it, the savings can be sizable.
Do Load Forecasting
DESS provides the tools to help you simulate and evaluate future load growth. The detailed load modeling available in DESS gives you comprehensive control over load modeling and scaling. By combining assumptions about growth in existing loads with modeling of new loads you can accurately model both the level of load and its effects on specific features and stations.
We recognize that our customers are busy. They don’t have time to take a week long training course to use the software, and they don’t want a steep relearning curve if they go back to the software after a break. One of the key design principles of DESS it that it be easy and intuitive to use.
Effectively Use GIS Data
Geographic information systems have become the standard way for recording and managing utility facilities data. DESS provides a return on investment on the effort invested in a GIS by using the data for system planning and loss reduction. As an additional benefit, by using the data for analysis DESS acts as a quality check on the GIS data and can help improve users’ confidence in the GIS data.
Perform Operational Planning
An accurate system model lets you simulate real system situations in software. For example, if you want to model the effects of losing a substation, or evaluate voltages under load transfer conditions, DESS can help you. You can try different options and even use DESS to plan contingencies for potential problems.
