水电富集电网大规模电站群发电调度系统设计及关键技术

System Design and Key Techniques for Large-Scale Power Plants Generation Dispatching of Power Grid with Rich Hydropower

我国水电系统高速发展使得单一电网集中调度的水电站规模超过100座甚至200座,如此大规模水电系统调度亟需切实可行可用的应用系统支撑,以高效科学地完成电网日常发电调度分析和计划编制工作。以水电富集的云南电网为例,从工程实用性出发,通过系统性架构设计,采用时序数据库集群协同数据存储和管理技术、大规模发电调度约束条件分类批量处理技术、调度报表可视化定制技术,开发了水电富集电网大规模电站群发电调度系统,并于2016年4月在云南电网得到了成功应用(包含水电站150余座),自系统投运后,显著提高了发电调度结果的可行性和发电计划编制效率。

Rapid development of hydropower system in China makes the number of hydropower plants in a centralized dispatching fashion 100 or even 200. To complete daily analysis and planning of power generation scheduling of such a large-scale hydropower system scientifically and efficiently, a practical application system is needed. Taking the Yunnan Power Grid with rich hydropower as background, a power generation dispatching system for large-scale power stations has been developed for real engineering through system architecture design. This system uses temporal database cluster data storage and management technology, large-scale power generation scheduling constraints batch processing technology and visual customization techniques of operation reports. The system and its key techniques have been used successfully in April 2016 in Yunnan Power Grid. More than 150 hydropower plants participated in the system operations. The actual operation results show that the generation dispatching system can significantly improve the feasibility of power generation results and computational efficiency.
