Utility System Simulation: A Nonlinear Approach

Abstract

Computer simulation of plant utility systems allows an engineer to rapidly 1) analyze operation changes, 2) analyze design changes, and 3) optimize the steam/electric system for the lowest operating cost. MESA (Modular Energy System Analyzer) is a PC-based computer program that can be configured to accurately simulate plant utility systems. MESA uses a modular modeling approach whereby the engineer "builds a specific plant model by arranging modules (boilers, turbines, deaerators, etc.) in a pattern that reflects the actual geographical location of the existing utility equipment. The computer prompts the engineer for specific information about each module. The interaction between modules is not required. A powerhouse with four boilers, four turbine generators, one gas turbine, and three pressure levels plus all auxiliary equipment can be modeled in less than four hours. MESA has been licensed commercially since 1982 and is in use at many of this country's largest industrial plants.
