The Open Source Hybrid Steady-state Simulator of Rankine Cycle in Python

PyRankine

The PyRankine is the hybrid steady-state simulator of Rankine Cycle in Python.

In the hybrid simulator, two kind of simulation approachs are provided:

• sequential-modular

• equation-oriented

Dependencies：SEUIF97

IAPWS-IF97 high-speed shared library

• https://github.com/PySEE/SEUIF97

Install

python -m pip install seuif97

The Example Rankine Cycle

The condensing steam cycle of a supercritical pressure 600MW generating unit is used as the case of example.

The condensing steam cycle has

• three turbines with four exhaust steams

• one sealing, four low pressure feedwater heaters, one open feedwater heater/de-aerator, and three high pressure closed feedwater heaters.

The Data File of the Example Cycle

The json file is used to representate the example cycle's flowsheet and data

Run

• simulation on 1kg mass

python rankinesim.py

• simulation on specified power/mass
