以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
为了说明本发明所述的技术方案，下面通过具体实施例来进行说明。
具体实现中，本发明实施例所描述的图数据库构建方法可由电子设备实现，电子设备可以是服务器、一般计算机等，此处不作限定。对本发明实施例以电子设备为执行主体进行描述。
请参见图1，是本发明实施例提供的图数据库构建方法的流程示意图。本发明实施例提供的图数据库构建方法可包括步骤：
步骤101、获取能源系统中的能源设备。
具体地，能源系统可以理解为是将自然界的能源资源转变为人类社会生产和生活所需要的特定能量服务形式(有效能)的整个过程，通常包括多个能源设备。本实施例中并不意图对能源系统中的能源设备的数量以及能源设备之间的关系做任何限定，任何能够进行能源转化的系统即可。在实际应用中，能源系统可以是综合能源系统。其中，综合能源系统指的是一定区域内的能源系统利用先进的技术和管理模式，整合区域内石油、煤炭、天然气和电力等多种能源资源，实现多异质能源子系统之间的协调规划、优化运行、协同管理、交互响应和互补互济，在满足多元化用能需求的同时有效提升能源利用效率，进而促进能源可持续发展的新型一体化能源系统。
具体地，能源设备具体指的是跟能源相关的设备，比如，生产能源设备、变换能源设备、传输能源设备、存储能源设备、使用能源设备、回收能源设备等。
步骤102、根据设备属性图模型，构建所述能源设备的设备属性图。
具体地，基于设备属性图模型以及能源设备，构建能源设备的设备属性图，从而得到用于描述能源设备的设备属性图。其中，设备属性图模型指示了如何描述能源设备和其属性。设备属性图为描述设备和其属性的结构图。
在一个实施例中，所述设备属性图模型包括设备顶点以及属性值顶点，所述属性值顶点和所述设备顶点通过属性连接，所述属性和所述属性值顶点对应。
可选地，步骤102包括：
当监听到所述能源设备的设备顶点添加事件时，添加设备顶点；
当监听到所述能源设备的属性值顶点添加事件时，添加属性值顶点；
当监听到所述能源设备和所述属性值顶点之间的属性添加事件时，添加所述设备顶点和所述属性值顶点之间的属性；
当判断需要继续添加所述能源设备的属性值时，执行所述当监听到所述能源设备的属性值顶点添加事件时，添加属性值顶点；
当判断不需要继续添加所述能源设备的属性值时，将所述判断不需要继续添加属性值时的设备顶点、各个属性值顶点以及各个属性值顶点各自连接设备顶点的属性，作为所述能 源设备的设备属性图。
可以理解的，设备顶点添加事件指的是外部输入为添加设备顶点，比如，用户点击新增设备顶点图标后，新增了空白的设备顶点，在空白的设备顶点输入设备名称，从而添加设备顶点，或者，用户输入设备名称后，点击新增设备顶点图标，得到设备顶点。属性值顶点添加事件外部输入为添加属性值顶点，比如，用户输入属性值后，点击新增属性值顶点，得到属性值顶点。属性顶点添加事件外部输入为添加属性，比如，用户输入属性后，点击新增属性，得到设备顶点和属性值顶点之间的属性，属性表示为边。
在实际应用中，用户通过现有技术中的图建模工具，增加设备顶点，在增加了设备顶点之后，增加设备顶点的属性值顶点，并以属性作为边连接设备顶点和属性值顶点，当需要继续增加属性值顶点时，重复增加属性值顶点，并以属性作为边连接设备顶点和属性值顶点，直到得到能源设备的设备属性图，示例地，请参考图5，图5示出了变压器的设备属性图，其中，变压器所在节点为设备顶点，特变、10kV、油浸式、双绕组、1000kVA所在节点均为属性值节点，品牌、额定电压、冷却类型、绕组形式、容量均为属性，设备顶点和属性值节点通过属性连接，属性值和属性相对应，属性表达为边。
举例来说，变压器的额定电压是10kV，其中，变压器是能源设备，额定电压是变压器的属性，10kV是属性值。需要说明的是，属性是符合公共信息模型标准的。其中，公共信息模型标准指的是用于描述能源设备、能源设备的属性、属性的属性值的标准名称，即对相同语义的实体采用相同的表达方式。
步骤103、根据拓扑网络图模型以及所述能源设备的设备属性图，构建所述能源系统的拓扑网络图。
具体地，基于拓扑网络图模型以及能源设备的设备属性图，构建能源设备的设备属性图，从而得到用于描述能源系统的拓扑网络图。其中，拓扑网络图模型指示了如何描述能源网络的结构。拓扑网络图指的是能源系统的结构图。
