Power Industry

The VariSim Suite supports some very powerful applications for the heat network industry that can be applied to any pipeline configuration – whether simple A to B pipelines or more complex steam networks. Desktop studies can be undertaken for designing, planning, troubleshooting and optimising.

If it is possible to obtain recorded data, VariSims dynamic simulator capabilities can provide a unique  insight  into  the  performance  of  a  steam network  and visibly  demonstrate  the  dynamic  interaction  of  the whole  pipeline  infrastructure – including the control schemes. This provides the ultimate environment for helping to solve the day to day design and safety requirements for steam systems.

Desktop Analysis

 

Use the powerful build processes to generate models of any heat network including simple A to B pipelines, branched pipelines or complex networks. Simulator models are created with VariBuild using the inbuilt user interface with graphical drag and drop functionality and/or the model build wizard that imports models from third party databases.

Design, Plan, Troubleshoot, Optimise
Starting conditions can be based on design data, field observed data or logger data depending on the objective of the study which can include:-

Steady state flow, pressure and temperature distribution for review

Dynamic hydraulic reaction to equipment operation, control schemes and demand changes.
Perform repeated simulations to optimise the operation of the pipeline / network and accurately size equipment across the range of transient pipeline conditions. Example optimisations include pipe sizing, compressor and turbine sizing, valve set-point and control system settings etc.


Measurement Driven Simulation

 

VariSim has the ability to use measured data to drive it. With this type of simulation, it mimics the real pipeline and is often termed an online simulator or a digital twin. The measurement data may be logger data so that it mimics the pipeline / network reaction at the time the logger data was recorded, or it can use current data (obtained through the connection to a live database) to make the simulator a real time simulator.

A real time simulator can transfer its current state to a copy of the simulator operating in a desktop environment. This allows the user to initiate the simulation with current conditions for subsequent simulation and analysis.

In reality, all steam networks are transient and in a state of flow and temperature imbalance. True transient simulation is essential for solving the conditions of imbalanced heat networks and a simulator that uses a steady state solution will frequently fail to achieve this.

Monitor, Detect, Optimise
View any VariSim calculated value at any location on the pipeline / network including flow, pressure, temperature, velocity, density, wavespeed, valve positions etc.
Obtain Virtual Instrumentation values at any location on the pipeline / system
Detect events and anomalies that develop on the steam network.
