摘要
以发电站的改扩建优化设计为工程背景,通过Lingo,Mathematic,Matlab等数值计算软件建立总装机量计算模型和装机顺序优化模型。以最少投资为原则建立目标函数,采用整数规划的思想,将整数规划问题转化为一般规划问题,继而采用趋势分析法,对用电需求进行预测,同时结合供电需求量和发电量两大约束条件,优化了建造顺序和建造时间。结果表明:第一阶段,扩建原有旧火电站,在项目开始即扩建2台单机容量为10 kW的发电机组;第二阶段,新建水电站,在第1.6 a和第2.7 a,各建设1台单机容量为25 kW的发电机组;第三阶段,新建火电站,在第3.8 a,第5.7 a,第7.3 a,第8.8 a各建设1台单机容量为30 kW的发电机组。优化设计为发电站的改扩建规划提供了可靠的指导依据。
Taking the extension and reconstruction of power station as research objects, the numerical calculation model of total installed capacity and optimization model of installed sequential are established through Lingo, Mathematic ,Matlab and other soflwares. In principle the investment is minimum, establish the objective function. Translate the integer programming problem into general programming problem through integer programming ideas. Evaluate the power demand using trend analysis. Optimize the construction sequence and construction time based on the power generating capacity and demand capacity. The results of numerical studies show that, in the first stage, extend the original power plant, install two generating units whose capacity are l0 kW at the beginning of expansion project. In the second stage, build new stations. In the 1.6 year and 2.7 year, separately build a generator sets whose capacity are 25 kW. In the third stage, build new power plants. In the 3.8 year,5.7 year,7.3 year and 8.8 year, separately build a generator sets whose capacity are 30 kW. The optimal design for the renovation and expansion of power station provide a reliable guidance.
