Steam power system modeling method and device for power-driven equipment selection

Abstract

Disclosed are a steam power system modeling method and a steam power system modeling device for power drive device type selection. The steam power system modeling method for the power drive device type selection includes: confirming performance indexes and technological parameters of all devices in a steam power system; building a first nonlinear mathematical model of the steam power system; generating a power drive device type selection alternative scheme and configuring corresponding parameters according to power drive power requirements of all portions in the steam power system and pressure level conditions of a steam pipeline at a position where a drive of a device to be selected is located; performing linear conversion between a solution of the first nonlinear mathematical model and the power drive device type selection alternative scheme, and generating a mixed integer linear mathematic model; judging whether the optimal power drive device design scheme meets an overall performance index of the steam power system according to an optimized solution of the mixed integer linear mathematic model; if the optimal power drive device design scheme meets the overall performance index, generating a second nonlinear mathematical model of the steam power system according to the optimal power drive device design scheme.

Description

technical field [0001] The invention relates to the field of steam power equipment, in particular to a steam power system modeling method and device for power-driven equipment selection. Background technique [0002] Motors and steam turbines, as the main power-driven equipment, are widely used in various large-scale industrial enterprises and thermal power plants. At present, the selection of power-driven equipment and the design or transformation of the corresponding steam power system mainly rely on the experience of technicians. [0003] In large-scale industrial enterprises, a large number of technological processes need to be driven by power, and electric motors or steam turbines need to be used as driving machines. The energy consumption caused by this part of the drive is huge. The design of drive type selection and steam power system is complex, and it is difficult to ensure the optimal design results by carrying out related design work based on experience. If th...

Problems solved by technology

The energy consumption caused by this part of the drive is huge

Drive type selection and steam power system design issues are complex, and it is difficult to ensure the optimal design results by conducting relevant design work based on experience

If there is a problem with the selection of the driving equipment itself, it will cause an unreasonable structure of the entire steam power system, resulting in additional energy and economic losses

For unreasonably designed steam power systems and unreasonably selected driving equipment, even if relevant operation optimization is used in operation, it can only be optimized on the basis of the existing process flow, and the effect is limited
