多用途低温核供热堆运行目标的开环优化研究

Study on Open-loop Optimization of Operation Target of Low Temperature Nuclear Heating Reactor in Multiple-purpose Configuration

为满足海边的工业开发小区在远离淡水网、热网时,由一座低温核供热堆动力厂提供小区全部淡化海水、供热、工业蒸汽和部分用电的需要,目标是在保证安全性的前提下,使低温核供热堆取得最佳的经济效益,达到运行经济性最优。本文采用开环优化的方法,研究低温核供热堆在负荷跟踪运行方式下的稳态运行目标,并为低温核供热堆负荷跟踪控制系统的分析设计提供负荷需求的输入参数。

A low temperature nuclear heating reactor （NHR） power plant is needed to provide all the resources including desalted water, heat and industrial steam, and part of electricity if a city near the sea is far away from fresh water supply network, power grid and heating network. The goal is to obtain the best economic benefits and to achieve the optimal economic operation under the precondition of ensuring the safety of low temper- ature nuclear heating reactor. In this paper, an open-loop optimization method was used to study the steady-state operation target of NHR under the load following operation mode, and to provide input parameters for the design analysis of NHR load following control system.
