【摘要】：针对太阳能辅助燃煤机组发电系统的不同耦合方式,基于循环函数法以及q-γ-τ矩阵,将太阳能热利用系统归并到机组主系统中,构造出不同耦合方式下热力系统质量单元进水系数矩阵方程,提出太阳能辅助燃煤发电系统单元进水系数通用矩阵模型,该模型全面反映机组主汽水系统结构以及太阳能辅助系统对整个热力系统的影响情况,且具有较强的规律性,使光煤一体化集成系统的热力特性与结构特性转化为计算机语言,使热力系统的分析计算程序化、精确化、简洁化,得出的矩阵方程具有普遍适用性。通过实例分析计算验证该方法的准确性,为太阳能规模化高效利用提供理论支撑。
[Abstract]:Aiming at the different coupling modes of solar assisted coal-fired generating system, the solar thermal utilization system is merged into the unit main system based on the cyclic function method and q- 纬-蟿 matrix. In this paper, the matrix equation of water intake coefficient of thermal system mass unit under different coupling modes is constructed, and a general matrix model of input coefficient of solar assisted coal-fired power generation system is presented. The model fully reflects the structure of the unit's main steam system and the influence of the solar energy auxiliary system on the whole thermal system, and has strong regularity. The thermodynamic characteristics and structural characteristics of the integrated optical coal system are transformed into computer language, and the analysis and calculation of the thermal system are programmed, accurate and succinct. The matrix equation obtained is of universal applicability. The accuracy of the method is verified by example analysis and calculation, which provides theoretical support for the efficient utilization of solar energy on a large scale.
