Steam turbine plant activation control device

Abstract

A steam turbine plant activation control device is provided, which generates an activation schedule that enables a reduction in a time period required for the activation of a steam turbine plant (1) without complex calculation such as prediction and calculation of a temperature and calculation of thermal stress. The activation control device (2) includes: a storage circuit (12) for storing a correlation between an initial value of a state amount parameter and a plant operation amount which includes a control reference value related to a control target amount and time lengths of phases in a process of activating the steam turbine plant; an operation amount determination circuit (13) for determining time lengths of phases and a control reference value based on the initial value of the state amount parameter and the correlation stored in the storage circuit; and an activation schedule circuit configured to generate activation schedules of the phases based on the phase time lengths and the control reference value, which are determined by the operation amount determination circuit (13), and generate an activation schedule for a time period from the start to the completion of the activation of the steam turbine plant by combining the activation schedules.

Description

technical field [0001] The invention relates to a start-up control device for steam turbine equipment. Background technique [0002] In order to protect petrochemical resources, power generation facilities using renewable energy such as wind power generation and solar power generation are increasing. In such power generation facilities, the amount of electricity obtained from renewable energy varies greatly depending on seasons, weather, and the like. In order to quickly compensate for such fluctuations in electric power and stabilize the power system, it is desired to shorten the start-up time (high-speed start-up) of such power generation facilities (steam turbine facilities) including steam turbines. [0003] In the start-up of steam turbine equipment, from the viewpoint of protecting the constituent devices of the steam turbine equipment from the start to the completion of the start-up, the thermal stress generated in the heated part such as the steam turbine or the ste...

AI Technical Summary

Problems solved by technology

However, in the start-up control of Patent Document 1, the start-up schedule is the same regardless of the elapsed time after stoppage in the same start-up mode, so although it is possible to start the steam turbine facility at a higher speed, it can only be specified in the start-up mode. Needs boot time to start

[0006] In the start-up control of Patent Document 2, the start-up schedule is determined by using simulation every time the steam turbine equipment is started up, so the temperature prediction calculation and thermal stress calculation are complicated, resulting in a large amount of calculation processing.
