【摘要】：蒸汽動(dòng)力系統(tǒng)多周期運(yùn)行燃料消耗量的計(jì)算方法通常先建立蒸發(fā)量與效率的關(guān)系模型,再由能量平衡方程得出。為簡(jiǎn)化計(jì)算,建立蒸發(fā)量和燃料量關(guān)系的雙燃料鍋爐數(shù)學(xué)模型。提出背壓式、抽背式汽輪機(jī)調(diào)優(yōu)規(guī)則:如果需要同時(shí)運(yùn)行兩臺(tái)以上相同型號(hào)的汽輪機(jī),則優(yōu)先最大負(fù)荷運(yùn)行數(shù)學(xué)模型斜率大的汽輪機(jī),斜率相等則任意分配負(fù)荷。汽輪機(jī)調(diào)優(yōu)規(guī)則擴(kuò)展到燃料量和蒸發(fā)量呈線(xiàn)性關(guān)系的單燃料鍋爐負(fù)荷分配:如果一次項(xiàng)系數(shù)相等,則蒸發(fā)量任意分配。否則,最大負(fù)荷運(yùn)行斜率小的鍋爐。針對(duì)粒子群算法收斂速度慢、早熟的缺點(diǎn),提出慣性權(quán)重對(duì)數(shù)遞減策略的粒子群算法。采用改進(jìn)的粒子群算法對(duì)建立的蒸汽動(dòng)力系統(tǒng)運(yùn)行優(yōu)化調(diào)度的混合整數(shù)非線(xiàn)性規(guī)劃模型進(jìn)行求解,節(jié)約了運(yùn)行成本,驗(yàn)證了算法的有效性和實(shí)用性。
[Abstract]:The calculation method of fuel consumption of steam power system in multi-period operation usually establishes the model of the relationship between evaporation quantity and efficiency, and then obtains from the energy balance equation to simplify the calculation. The mathematical model of double-fuel boiler is established, and the optimization rule of back-pressure and back-to-back steam turbine is put forward: if two or more steam turbines of the same type need to be operated at the same time. Then the steam turbine with high slope in the mathematical model of maximum load operation is preferred. If the slope is equal, the load distribution is arbitrary. The optimization rule of steam turbine is extended to the load distribution of single fuel boiler with linear relationship between fuel and evaporation: if the coefficient of one term is equal, the evaporation is arbitrarily distributed. Otherwise. Boiler with small slope of maximum load operation. Aiming at the shortcomings of particle swarm optimization (PSO), such as slow convergence speed and premature convergence. The improved particle swarm optimization algorithm is used to solve the mixed integer nonlinear programming model for the optimal scheduling of steam power system, which saves the running cost. The validity and practicability of the algorithm are verified.
