Description

一种电网图形及模型扩展方法
技术领域
本发明涉及电力系统调度自动化技术领域，具体是指一种电网图形及模型扩展方法。
背景技术
电网是指电力系统中各种电压的变电所及输配电线路组成的整体，称为电力网，它包含变电、输电、配电三个单元；电力网的任务是输送与分配电能，改变电压，电网图形就是将输送和配电过程模块化更好的管理、统计和分配电能量，电能量计量系统对电量数据的准确性有很高的保证，可以为线损、网损的计算以及电费结算提供可靠的基础数据。
现有的发电方式不仅仅是单一的火力发电，水利发电，风力发电，太阳能发电厂，核能发电都在快速的发展，且家庭清洁能源自助发电也在快速的研发中，故电网图形及模型建立如果还以一个发电厂为单位，会越来越有局限性，如果以一个用电地域为单位，如一个县或一个区来构建电网图形，以用电单位为模型基础，会更加符合电力系统未来的发展需要。
发明内容
针对上述情况，为克服现有技术的缺陷，本发明提供了一种电网图形及模型扩展方法，为区域用电管理调度人员提供参考并合理配置。
本发明采取的技术方案如下：本发明是一种电网图形及模型扩展方法，包括如下步骤，
(S1)以用电区域为单位，根据本区域内发电厂情况，根据电能量计量系统需求，确认需要展示的模型；
(S2)建立模型和模型之间的连接关系，即建立各个发电厂、变电站、线损、网损和用电单位的连接关系，生成电网图形；
(S3)通过电量系统模型创建规则找到电网图形中计量点与电量系统模型的关联关系并展示。
进一步地，所述步骤(S1)包括如下步骤：
(S1-1)以用电区域为单位：将用电区域作为模型建立整体，统计各个用电单位基础用电数据，整合用电单位数据并作为基础模型；
(S1-2)根据本区域内发电厂情况：统计在本区域内发电厂数量和发电情况，根据不同发电厂类型，在不同天气和季节差异整合不同时间段发电数据；
(S1-3)根据电能量计量系统需求：利用常使用的潮流图、调度用图、监控用图以及目录图作为统计基础；
(S1-4)确认需要展示的模型：确定模型种类和数量。
采用上述结构本发明取得的有益效果如下：以区域为单位进行电网系统管理相较以发电厂为单位进行电网系统管理，更加符合现有多种发电方式并存的实际情况，调度人员可根据实际天气和季节情况整合调度，并且可调度发电厂的发电量，在保证供电正常的情况下，优先选择清洁能源发电厂，综合各项数据减少火力发电量，保护资源和环境；以用电单位作为模型建立的主体，通过以往用电量反馈作为发电量的参考数据，将线损和网损加入模型当中，网损和线损虽是不可避免的，但也是可以被减少的，将此作为模型，方便后续合理分配变电站位置，更加合理的配置资源，尽可能减少线损和网损。
具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例；基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例，本发明提供一种电网图形及模型扩展方法，包括如下步骤：
步骤S1包含四个步骤：
1.将用电区域作为模型建立的整体，打破原本以某个发电厂为整体单位的模式，统计各个用电单位基础用电数据，抓取过去两年用电单位不同季节和不同时间段的用电数量，整合数据和规律，作为数据模型的基础并作为主模型。
2.统计在本区域内发电厂数量和发电情况，如风力发电厂过去两年发电量和使用情况，水利发电厂过去两年发电量和使用情况，太阳能发电厂过去两年发电量和使用情况，核能发电厂过去两年发电量和使用情况，综合计算本区域内发电厂在不同季节和时间段的发电能力。
3.利用常使用的潮流图、调度用图、监控用图和目录图作为统计方法，配合各自的配置文件和数据库，加入之前统计的用电单位用电数据和区域内发电厂的发电数据。
4.整合各类资源和数据，综合计算，确认模型和数量。
步骤(S2)将网损和线损加入模型当中，作为重要研究对象，将发电厂、变电站、网损、线损和用电单位各个模块关系建立，形成电网图形。
步骤(S3)通过电量系统模型创建规则找到电网图形中计量点与电量系统模型的关联关系，通过综合计算，综合调度，在不同季节，天气和时间段，合理配置发电厂的发电情况，在保证供电正常的情况下，尽量采用清洁能源发电。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
