Problems solved by technology

In order to avoid missing operations, the operator on duty usually finds the power change time points and fills in the power up and down record card after receiving the power curves for the next day or consecutive days, and manually sets the alarm for each operation time point The traditional alarm setting software is aimed at the mass users, and the alarms can only be set manually one by one. The repetitive workload is heavy and time-consuming, and omissions and mistakes are prone to occur during the process. , cannot effectively adapt to the needs of on-site work

Embodiment

[0023] 1) The software reads the selected power plan curve file, obtains the power value every 15 minutes today, judges and records the power change time point, that is, the time point when the power up and down operation is to be performed throughout the day; for the last time point of the previous day, Judgment based on today's first power value; 2) Display all alarm reminder times and alarm validity status list, which will automatically update the alarm validity status after the alarm reminder event occurs; 3) Periodically check the alarm Whether the time arrives, if it is reached, the sound file will be played to remind; 4) Monitor the alarm ringing time, if it exceeds 1 minute, the computer buzzer will sound, this method is used as a backup reminder method for reminding by playing sound through the speaker; 5 ) The software periodically records the computer system time and compares it with the system time recorded in the previous period. If the difference is not equal to t...

Abstract

The invention relates to a method for setting an alarm for convertor station power increasing and decreasing. The method comprises the following steps that first, the alarm is set according to a power curve file; second, computer system time is monitored, whether a difference value between the time and recorded time in the previous period is generated is judged, if yes, the effectiveness of the alarm set before is checked according to the current system time, time of the alarm is set again, the second step continues to be executed, and if not, a third step is executed; third, alarm reminding is conducted at the set alarm moment; fourth, whether an alarm ring is confirmed within the set time is judged, if yes, a sixth step is executed, and if not, a fifth step is executed; fifth, a computer buzzer conducts reminding, and then the sixth step is executed; sixth, a user confirms stop of the reminding, and a power lifting record card is filled in automatically. Compared with the prior art, the method has the advantages of making setting convenient and concise, reducing errors, being safe and reliable and the like.

Description

technical field [0001] The invention relates to a method for setting an alarm clock, in particular to a method for setting an alarm clock for power up / down operation of a converter station. Background technique [0002] HVDC transmission has the characteristics of fast and controllable power. In the actual work of the converter station, daily manual power up and down operations are very frequent, and every 15 minutes is a power operation time point. From the beginning of 2013, the Huaxin converter station started daily There are nearly 30 lifting operations at most, and the distribution of power lifting and lowering times is scattered, not all in a continuous time period. In order to avoid missing operations, the operator on duty usually finds the power change time points and fills in the power up and down record card after receiving the power curves for the next day or consecutive days, and manually sets the alarm for each operation time point The traditional alarm setting...
