The basic information of the grid engineering is stored in the form of a two-dimensional table.

电网工程时段为从该工程规划到投在线的时段,假设电网工程为新建一个厂站,新建厂站的规划到投在线的时段即为该工程时段。The time period of the power grid project is the time period from the project planning to the on-line operation. Assuming that the power grid project is a new plant, the time period from the planning of the new plant to the on-line operation is the project time period.
步骤2:根据需求选择未来时刻,将未来时刻及之前的电网模型未来变更信息和当前电网模型进行时序化动态叠加计算,得到未来时刻的电网未来模型。Step 2: Select the future time according to the demand, and perform the sequential dynamic superposition calculation on the future time and the previous grid model future change information and the current grid model to obtain the future grid model at the future time.
时序化动态叠加计算的公式:电网未来模型=当前电网模型+电网模型未来变更信息中的新增模型-电网模型未来变更信息中的删除模型+电网模型未来变更信息中的参数修改值。The formula for sequential dynamic superposition calculation: future grid model = current grid model + new model added in future change information of grid model-deleted model in future change information of grid model + parameter modification value in future change information of grid model.
电网工程时段根据时间依次划分成若干个阶段,如图2一般分为规划阶段、 计划阶段和运行阶段,3个阶段可作为未来时间的断面,不同阶段电网模型未来变更信息时序化动态叠加隔离计算,每个阶段获得相对独立的电网未来时刻模型。后面阶段的电网未来模型变更信息可继承前面阶段的电网未来模型变更信息,实现电网未来模型不同阶段的参数复用,减少重复劳动提高工作效率,提升多专业用户协同维护电网未来模型的能力。The power grid engineering period is divided into several phases according to time. As shown in Figure 2, it is generally divided into planning phase, planning phase and operation phase. The three phases can be used as sections of the future time. The future change information of the power grid model in different phases is time-series dynamic superimposed and isolated calculation , Each stage obtains a relatively independent grid future moment model. The future model change information of the power grid in the later stage can inherit the future model change information of the power grid in the previous stage, realize the parameter reuse of different stages of the future model of the power grid, reduce repetitive labor, improve work efficiency, and improve the ability of multi-professional users to coordinate the maintenance of the future model of the power grid.
电网工程的规划阶段仅建立和维护主设备模型、建立典型参数、建立拓扑,偏向于框架性计算建模。计划阶段指规划工程开工建设至新设备开启调度命名阶段,用户(计划专业用户)创建的电网未来模型,其中线路、变压器等规划阶段中已建设设备参数可直接从规划阶段的电网未来模型变更信息继承,并赋以调度命名及维护铭牌参数,同时建立详细母线、断路器、闸刀、容抗器等设备及其相关参数(如位置属性)、拓扑。运行阶段主要指设备启动投运阶段,该阶段需补充设备实测参数并上传实测报告,供用户随时比较录入参数与实测报告的差,需补全计划阶段未录入的设备铭牌参数,管理参数、运行状态参数等其它参数可由继电保护、系统运行等专业录入审核。The planning stage of power grid engineering only establishes and maintains the main equipment model, establishes the typical parameters, and establishes the topology. It is biased towards framework calculation modeling. The planning stage refers to the future model of the power grid created by the user (planned professional user) from the start of construction of the planning project to the start of the scheduling and naming of the new equipment. The parameters of the built equipment in the planning stage such as lines and transformers can be directly changed from the future model of the power grid in the planning stage. Inherit, assign scheduling naming and maintain nameplate parameters, and establish detailed bus, circuit breaker, knife, capacitive reactor and other equipment and related parameters (such as location attributes) and topology. The operation phase mainly refers to the equipment start-up and commissioning phase. In this phase, it is necessary to supplement the actual measurement parameters of the equipment and upload the actual measurement report for users to compare the difference between the entered parameters and the actual measurement report at any time. The equipment nameplate parameters that are not entered in the planning phase need to be supplemented, management parameters, and operation Other parameters such as status parameters can be entered and reviewed by professionals such as relay protection and system operation.
步骤3:将电网未来模型导入电网未来模型文件共享。Step 3: Import the grid future model into the grid future model file sharing.
该电网未来模型文件主要是给与电网调控中心相关联的系统共享,通常为二进制文件或CIM/E文件等。The future model file of the power grid is mainly shared by the system associated with the power grid control center, usually a binary file or a CIM/E file.
步骤4:投在线时,基于电网模型未来变更信息,批量变更当前电网模型。Step 4: When putting online, based on the future change information of the grid model, batch change the current grid model.
以电网模型未来变更信息为基础,工程管理服务自动生成批量模型维护语句,修改当前运行系统模型,在此基础上,实现导出相关电网未来模型全量和增量内容的CIM/E格式文件,用于投产至电力安全一区相关业务系统。Based on the future change information of the power grid model, the engineering management service automatically generates batch model maintenance statements, and modifies the current operating system model. On this basis, the CIM/E format file of the full and incremental content of the relevant future model of the power grid is exported for use Put into production to the related business system of Power Safety Zone 1.
客户端可通过C++/Java接口访问并查看未来时刻电网模型,其中Java接口 与行业内JDBC/Spring接口相兼容,C++接口与行业内OCI接口相兼容。客户端将SQL查询语句传入服务端,服务端采用基于lex和yacc的自研SQL解析器,对客户端传入的SQL语句进行SQL语法分析及语义级分析,得到相应的电网未来时刻模型信息返回给客户端。客户端可通过C++/Java接口访问并查看未来时刻电网模型,方便当前模型维护工具快速移植为未来模型维护工具,满足各类应用通过SQL语句获取数据的编程模式,有利于现有应用程序快速移植。The client can access and view the power grid model in the future through the C++/Java interface. The Java interface is compatible with the JDBC/Spring interface in the industry, and the C++ interface is compatible with the OCI interface in the industry. The client sends SQL query statements to the server, and the server uses a self-developed SQL parser based on lex and yacc to perform SQL syntax analysis and semantic level analysis on the SQL statements passed in by the client to obtain the corresponding power grid model information in the future. Return to the client. The client can access and view the power grid model in the future through the C++/Java interface, facilitating the rapid migration of the current model maintenance tool to the future model maintenance tool, satisfying the programming mode of various applications to obtain data through SQL statements, which is conducive to the rapid migration of existing applications .
服务端的模型存取服务可以统一负责所有电网未来时刻模型信息存取工作,模型存取服务根据客户端传入的工程ID区分用户所浏览与维护的未来模型维护工程,获取用户所查询与维护的未来时刻。The model access service on the server side can be responsible for the unified access to the model information of all power grids in the future. The model access service distinguishes the future model maintenance projects browsed and maintained by the user according to the project ID passed by the client, and obtains the query and maintenance of the user Moments in the future.
服务端与客户端基于Protobuf实现跨语言、跨平台的数据交互,基于RPC调用实现远程服务调用获取未来电网模型数据。客户端实现映射规则类处理行映射规则,将数据中每一行数据封装成固定或用户定义的类,以实现与行业内JDBC/Spring接口相兼容。The server and the client implement cross-language and cross-platform data interaction based on Protobuf, and implement remote service calls based on RPC calls to obtain future power grid model data. The client implements the mapping rule class to process row mapping rules, and encapsulates each row of data in the data into a fixed or user-defined class to achieve compatibility with the JDBC/Spring interface in the industry.
如图3,例如Level1为在2019年12月新建厂站A,与当前电网模型无交集;Level2为在2020年6月对现有厂站B改造,与当前电网模型有重叠;Level3为在2020年12月对A、B厂站模型进行改造,与Level1及Level2未来模型均有重叠。As shown in Figure 3, for example, Level1 means the newly built station A in December 2019, which has no intersection with the current power grid model; Level2 means the renovation of the existing station B in June 2020, which overlaps with the current power grid model; Level3 means that it is in 2020 The model of plant A and B was reconstructed in December 2015, which overlaps with the future models of Level1 and Level2.
当客户端指定查询2019年12月模型时,服务端将当前电网模型+厂站A新增模型,叠加计算得到2019年12月电网未来模型后返回给客户端。When the client specifies to query the December 2019 model, the server will add the current power grid model + the new model of plant A, superimpose the calculation to obtain the December 2019 power grid future model and return it to the client.
当客户端指定查询2020年6月模型时,服务端将当前电网模型+厂站A新增模型+改造厂站B模型变更信息,叠加计算得到2020年6月电网未来模型后返回给客户端,其中与当前电网模型重叠数据使用Level2模型数据。When the client specifies to query the June 2020 model, the server will return the current power grid model + the new model of plant A + the model change information of the modified plant B to the client after superimposing the calculation to obtain the future model of the power grid in June 2020. The data that overlaps with the current power grid model uses Level2 model data.
当客户端指定查询2020年12月模型时,服务端将当前电网模型+厂站A新增模型+改造厂站B模型变更信息+A、B厂站模型变更信息,叠加计算得到2020 年12月电网未来模型后返回给客户端,其中与Level1及Level2未来模型重叠数据使用Level3模型数据。When the client specifies to query the December 2020 model, the server will add the current power grid model + the new model of plant A + the change information of the modified plant B model + the change information of the model of plant A and B, and the superposition calculation will get December 2020 The future model of the power grid is then returned to the client, where the data overlapped with the Level1 and Level2 future models uses the Level3 model data.
客户端的具体操作过程如下:The specific operation process of the client is as follows:
1)客户端创建电网工程,并设定电网工程基础信息;不同阶段用户创建不同类别的子工程,例如,运行方式专业用户创建规划工程,计划专业用户创建新设备启动工程。1) The client creates a power grid project and sets the basic information of the power grid project; users at different stages create different types of sub-projects, for example, professional users create planning projects for operating modes, and professional users plan to create new equipment startup projects.
2)在客户端使用界面工具,界面工具通过客户端C++/Java接口向服务端传入变更SQL语句,服务端解析并存储电网模型未来变更信息。2) Use the interface tool on the client. The interface tool transmits the change SQL statement to the server through the client C++/Java interface, and the server parses and stores the future change information of the power grid model.

在获得未来时刻电网模型过程中,后面阶段的电网未来模型变更信息可继承前面阶段的电网未来模型变更信息,比如要获得计划阶段子工程相应的未来时刻电网模型,可先继承规划阶段的新增、退役、参数修改等增量变更信息,在此基础上获得所需的电网未来模型。In the process of obtaining the power grid model in the future, the future model change information of the power grid in the later stage can inherit the future model change information of the power grid in the previous stage. For example, to obtain the corresponding future time grid model of the sub-project in the planning stage, the new addition in the planning stage can be inherited first Incremental change information such as, decommissioning, parameter modification, etc., on this basis, obtain the required future model of the power grid.
客户端在完成电网未来模型维护、审核后,可根据实际投在线时间,将电网未来模型投入当前运行系统,在此基础上导出相关电网未来模型全量和增量内容的CIM/E格式文件,用于投产至电力安全一区相关业务系统。After completing the maintenance and review of the future model of the power grid, the client can put the future model of the power grid into the current operating system according to the actual online time, and export the CIM/E format file of the full and incremental content of the relevant future model of the power grid on this basis. The relevant business system in the first area of power safety is put into production.
