摘要
新能源电站自动化系统相互独立,数据结构和通信方式各异,制约了新能源电站电网适应性的提升。提出一种提升新能源电站电网适应性的功率协调控制思路:首先,建立统一的信息模型将新能源电站的相关信息进行有机融合,实现多源异构数据的友好交互;其次,将监控、功率预测、有功控制和无功控制的功能模块集成,实现不同功能模块的相互协调,提升电站控制的合理性和精细化水平。最后,研发了新能源电站智能功率控制系统,通过实际应用,验证了系统的可靠性。
Automation systems in renewable energy power station are mutually independent with different data structure and communication modes.So it is a key constraint in improving the power grid adaptability for renewable energy power station.One thought for power coordinated control is proposed to improve the power grid adaptability for renewable energy power station.Firstly,a unified information model is established for the organic fusion of related data in the renewable energy power station to realize the friendly interaction of multi-source heterogeneous data.Then,function models of monitoring,power prediction,active power control and reactive power control are integrated to realize the coordination and enhance the rationality and fine level of power control.Finally,an intelligent power control system of renewable energy power station is designed and developed and its reliability is validated through actual application.
