For example, the Chinese patent document with the application number 201310114561.X discloses a power system grid operation status monitoring and analysis system and monitoring and analysis method, which are used for grid operation status monitoring, analysis and early warning systems, but the technical solution does not involve the analysis of electric power Device or method for remotely monitoring information error causes of system accidents
For example, the Chinese patent document with the application number of 201510075099.6 discloses a power system monitoring alarm information processing method and system. However, although the technical solution identifies whether an alarm event has occurred through the alarm information and improves the analysis efficiency of the power system alarm information, it does not analyze errors. The reason for the alarm information cannot improve the efficiency of information elimination, which is not conducive to timely maintenance of the correctness and integrity of monitoring information

Embodiment Construction
[0031] Such as figure 1 As shown, the implementation steps of the method for identifying the cause of the remote monitoring information error of the power system accident in this embodiment include:
[0032] 1) Receive the actual situation of the power system accident reported by the operation and maintenance personnel of the substation, and check the accident opening signal one by one according to the actual situation of the power system accident. For each accident opening signal, if the accident opening signal is inconsistent with the actual situation of the power system accident, Then jump to step 2) to distinguish the cause of the power system accident remote monitoring information error, otherwise exit;
[0033] 2) If the actual situation of the accident has occurred, but there is no accident opening signal at the time of the accident and the accident position, then skip to step 3), otherwise, skip to step 14);
[0034] 3) It is determined that the accident opening signa...

The invention discloses an electric power system accident remote monitoring information error reason analyzing method. The electric power system accident remote monitoring information error reason analyzing method comprises steps that an electric power system accident actual situation reported by a substation operation and maintenance staff is received, and accident opening signals are checked in a one-by-one way by aiming at the electric power system accident actual situation; when the accident opening signals are inconsistent with the electric power system accident actual situation, electric power system accident remote monitoring information error reason analysis is carried out; according to the different situations such as the missing transmission and the error transmission of the accident opening signals, whether accident total signals, protection motion outlet signals, and a switch tripping location signal of a substation at a corresponding moment are missed is checked sequentially, and telemeasuring data is checked, and then the reason causing the accident remote monitoring information error is analyzed and determined in a layer-by-layer way. Equipment or information links causing the accident opening signal error can be analyzed and located according to remote monitoring signals of a scheduling main station, and a clear direction is provided for subsequent shortcoming elimination, and therefore the modification efficiency of the monitoring information is improved, and the timely performance of the maintenance of the remote monitoring information is guaranteed.
Description
technical field [0001] The invention relates to electric power dispatching automation technology, in particular to a method for identifying causes of electric system accident remote monitoring information errors. Background technique [0002] With the expansion of the power grid, the degree of automation and intelligence of the power system is deepening. At present, most of the substations in the power grid have been unattended. Personnel remote monitoring. The accuracy and completeness of the remote monitoring information of the power system, especially the monitoring information related to the accident, is of great significance to the timely detection and disposal of the accident, and even the safe and stable operation of the power system. In order to more intuitively and accurately reflect the power system accident situation, the new generation of smart grid regulation and control technical support system (dispatch master station) has combined the substation accident tot...
