【摘要】：遼寧電網(wǎng)供熱季節(jié)電網(wǎng)調(diào)峰壓力巨大,在保證供熱質(zhì)量的前提下盡可能降低供熱機組電負荷,并合理安排電量計劃,可最大限度地消納風(fēng)電。文中基于供熱機組"以熱定電"在線監(jiān)測系統(tǒng),提出了能量平衡法。通過對進出汽輪機的能量進行平衡計算,確定不同采暖抽汽熱量和工業(yè)抽汽熱量下機組發(fā)電量的關(guān)系,可以準確計算出一段時間內(nèi)機組在給定的采暖抽汽熱量和工業(yè)抽汽熱量下的最大電量和最小電量范圍。通過實際應(yīng)用驗證了該方法的準確性和實用性。
[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.
