IWLive Pro

IWLive Pro is an Innovyze product building upon the InfoWorks WS Pro product.

IWLive Pro is designed for use in the control room as an aid to predicting problem areas and assessing solutions to these problems. Uses of the product include:

• Continuous monitoring of supply networks.
• Automatic prediction of likely problems based on forecast demand.
• Evaluation of possible solutions to real or anticipated problems.
• Planning and training in the control room.
• Devising schemes, for example to reduce financial and carbon costs of supply.

A schedule of runs is created to carry out simulations using models that have been built and calibrated in InfoWorks WS. Models are updated automatically from live data so that each simulation begins with up-to-date reservoir levels and pump and valve status. Calendar and weather feeds are used to project anticipated demand in order to assess potential problems.

When a simulation is completed, results are processed and any warnings are displayed on the control room map. The map displays polygons representing the regions for which the control room is responsible. A highlighted polygon on the map indicates a prediction of problems in the next few hours, and a grid displays the time of onset of these problems.

The control room operator can then open a detailed map of assets in the highlighted region. The control status of objects such as valves and pumps can be changed on the map and further simulations can be run in order to evaluate possible solutions.

IWLive objects

There are several master database items that are used by IWLive. These objects are visible in the tree view in the Model Group window, but some of the objects can only be viewed and edited if the IWLive Pro option is enabled on your licence.

The objects used by IWLive Pro are:

• Baseline (version controlled) - Used to set up schedule for running simulations for a single model network.
• IWLive switch controller - Used to set up links to weather feeds and to set up calendar data.
• Warning template - Used to state the criteria that define an event, or an occurrence within the network, for example, critical pressure at a node. Events will trigger a warning in IWLive Pro.
• IWLive Run Info - Created by IWLive Pro, read only items containing run information for IWLive Pro projection, incident and response runs.
• Projection Run - Created by IWLive Pro, the projection runs contain simulations scheduled by a baseline object.
• Incident Run - Created by IWLive Pro, the incident runs contain simulations created in the IWLive Pro Operator program.

In addition, the Live Data Logon and Live Data Feed grids in the live data configuration are used to specify connections to one or more telemetry databases containing live data feeds.
