基于厂级调度的发电厂优化控制

为了实现发电厂单元机组有功的经济分配和保证区域电压质量,适应厂网分开和经济调度的要求,结合直调方式下的系统设计和设备配置,将厂级负荷分配模块集成到电厂的电气网络监控系统中,与系统中原有的电厂侧电压无功控制系统,构成火电厂综合优化控制系统,2个模块在实现自身功能的同时,也可以互相交换信息,实现有功的经济调度和无功的优化分配;同时为了使调度端获取更多的电厂侧的信息,在监控系统中建立了基于CIM的励磁系统模型,更好地保证了电厂侧AVC控制的准确性和安全性。

Optimal Control of Power Plant Based on Plant Level Dispatching

In order to achieve the economic distribution of the plant＇s power and ensure area voltage quality,and meet the requirements of deregulation and economic dispatch,a collaborative optimization control system is proposed in this paper.Combining the system design of direct transfer mode and equipment configuration,this system is constructed with electrical network monitoring system integrated of plant level load distribution module and original plant＇s voltage reactive control system.The system can not only realize the function of itself,but also exchanges information with each other to achieves active power economic dispatch and reactive power optimization distribution.In order to obtain more information from power plant side,excitation system model based on CIM is built in network monitoring control system,which guarantees the accuracy and security of AVC control on the power plant side.
