Description

风电场功率预测系统虚拟测风塔装置
技术领域
本发明涉及的是风电生产运营技术领域，具体涉及一种风电场功率预测系统虚拟测风塔装置。
背景技术
随着风电装机容量规模的快速增长，并入电网等问题越来越突出，而风能具有独特的波动性、间歇性和反调峰性特性，这些特点所导致的风电功率波动，会对地区电网整体运行产生影响。通过风功率预测进行结果预测，可为电网提供安全性和可靠性以及电网接纳风的能力。 随着各区域能监局出台“两个细则”，各区域考核规则中均有功率预测数据上报率的要求，如果数据上报率达不到相关要求，则会对风电场进行考核。测风塔数据的上报也逐渐纳入考核的范围内，因此，测风塔数据的连续性，完整性也关系到风电场的整体考核。
综上所述，本发明设计了一种风电场功率预测系统虚拟测风塔装置。
发明内容
针对现有技术上存在的不足，本发明目的是在于提供一种风电场功率预测系统虚拟测风塔装置，弥补了风场因为地形环境无法安装测风塔的问题，或者因为现有测风塔故障数据中断的问题。该虚拟测风塔装置的使用，可以保证测风塔数据的连续性，保证测风数据的实时更新以及上传电网的上报率。虚拟测风塔装置的应用，提高了风电场测风数据的连续性和完整性，有效的避免了因为测风塔故障或者通信问题造成的数据考核，提升了功率预测系统的整体效率。
为了实现上述目的，本发明是通过如下的技术方案来实现：风电场功率预测系统虚拟测风塔装置，包括虚拟测风塔装置和子站外网，虚拟测风塔装置通过网线连接在风电场功率预测子站外网，子站外网通过正向隔离、反向隔离与子站内网相连；所述的子站外网和虚拟测风塔装置的ip设置为同网段，保证了通信正常。
作为优选，所述的虚拟测风塔装置通过网线采集测风塔数据。
作为优选，所述的虚拟测风塔装置的数据通过U盘等方式导出。
作为优选，所述的虚拟测风塔装置通过网线连接在风电场功率预测子站外网，通过网络tcp协议和服务器进行数据和信息交互。
本发明具有以下有益效果：
1、实时监测测风塔数据
风电场存在真实测风塔时，可以通过网络实时监测目前测风塔数据，当测风塔数据不刷新或者规定时间间隔内没有数据，虚拟测风塔数据会自动切换为虚拟测风塔数据以代替真实的测风塔；当真实测风塔数据恢复后，虚拟测风塔自动结束虚拟数据。
2、代替真实测风塔
风电场因为地形等无法安装测风塔或者测风塔故障时，虚拟测风塔可以根据风电场现有的风机数据、气象数据、地形地貌等数据综合模拟出风电场的测风塔数据，并将该数据按照要求上报至电网侧。
3、参与风资源评估
分散式风电整体建设时，风资源评估比较困难，同时该开发过程中没有测风塔，却需要相对精准的风资源评估。通过本虚拟测风塔装置，可以相对准确的参与风资源评估，在提高风资源数据准确率的同时，也降低了风电场开发建设的成本。
4、数据存储与展示
虚拟测风塔装置可以按照指定频率进行数据发布与存储，存储的数据可以支持多种方式导出展示，同时也可以对模拟数据进行简单分析展示，可以使用户快速的掌握数据质量。
