Embodiment

[0017] Such as figure 1 As shown, it is a flow chart of the method for implementing the aggregation operation of IEC61970 historical data.

[0018] For the historical data that has undergone data compression on August 5, 2013, the root mean square is calculated at intervals of 5 minutes, including the following steps:

[0019] (a) Set filter conditions for historical data, filter conditions include start time, end time and interval time. The start time and end time indicate the total amount of data, that is, which historical time period the data needs to be read is in; the interval time indicates the amount of data for each aggregation operation, that is, the unit of time for the operation.

[0020] The start time is 00:00:00 on August 5, 2013, the end time is 23:59:59 on August 5, 2013, and the interval is 5 minutes.

[0021] (b) Perform basic aggregation operations while traversing historical data according to filter conditions. Use the historical data specified by the st...

Abstract

The invention discloses a collection operation achievement method of IEC61970 history data, and relates to the technical field of energy management systems in an electrical power system. The method includes the following steps that a filtering condition of the history data is set, a basic collection operation is conducted while the history data are traversed according to the filtering condition, and the result of collection operation is computed according to the basic collection operation result. By means of the collection operation achievement method, the computing efficiency and computing speed of a distribution system can be improved, the normal operation of the distribution system can be guaranteed timely, failures and economic losses are avoided, resources of the distribution system are saved, and development and maintenance cost of the distribution system is reduced.

Description

technical field [0001] The invention relates to the technical field of energy management systems in power systems. Background technique [0002] With the advancement of science and technology, various applications within the energy management system and between the energy management system and other systems realize data communication through IEC61970. Based on IEC61970 (the "Energy Management System Application Programming Interface (EMS-API)" series of international standards formulated by the International Electrotechnical Commission), it supports OMG HDAIS data interface and aggregation operations to achieve high-speed historical data access and statistical processing of historical data. The method for implementing the aggregation operation of historical data. In the distribution network system, it is necessary to form historical data into reports, and perform statistical calculations on the reports in the distribution network system. Usually the amount of historical da...
