【摘要】：辽宁电网供热季节电网调峰压力巨大,在保证供热质量的前提下尽可能降低供热机组电负荷,并合理安排电量计划,可最大限度地消纳风电。文中基于供热机组"以热定电"在线监测系统,提出了能量平衡法。通过对进出汽轮机的能量进行平衡计算,确定不同采暖抽汽热量和工业抽汽热量下机组发电量的关系,可以准确计算出一段时间内机组在给定的采暖抽汽热量和工业抽汽热量下的最大电量和最小电量范围。通过实际应用验证了该方法的准确性和实用性。
[Abstract]:The peak load of Liaoning power grid is huge in heating season. Under the premise of ensuring heating quality, the electric load of heating unit can be reduced as much as possible, and the electricity quantity plan can be arranged reasonably, which can absorb wind power to the maximum extent. Based on the on-line monitoring system of heating unit, the energy balance method is put forward. Through the balance calculation of the energy in and out of the steam turbine, the relationship between the generating capacity of the unit under the different heating extraction heat and the industrial extraction heat is determined. It is possible to calculate accurately the range of maximum and minimum electric energy of the unit under the given heating extraction heat and industrial extraction heat for a period of time. The accuracy and practicability of the method are verified by practical application.
