Problems solved by technology
[0011] The above steps of the discharge are all manual operations. The voltage measurement and recording during the discharge process is more labor-intensive, and the accuracy of the measurement is even more difficult to grasp.
In particular, the monitoring during the discharge process and the judgment of abnormal conditions are all carried out manually, and its accuracy and timeliness cannot be guaranteed.

Embodiment Construction
[0033] First, through the battery monitoring equipment, data such as group voltage of the battery pack, single voltage, current, temperature, and AC input voltage are collected, and at the same time, the real-time status of switches such as bus tie, bus switch, battery, discharge, and charge, or switches are collected. Then process the data state, specifically, through the principle of time-sharing processing, selectively monitor and analyze the key state data, increase the defibrillation time and other processing strategies, so that the instance can stably feedback the current state of the battery pack, which is a one-button Discharge provides safe state judgment support.
[0034] The basis for the automatic execution of one-key discharge comes from the sequence control template table, which is pre-configured and then saved in the database. The overall process is as follows:
[0035] (1) Read the one-key discharge sequence control template table;
[0036] (2) Execute each op...

The invention relates to a one-key discharge method for a storage battery of a transformer station, and the method is characterized in that the method comprises the following steps: building a sequential control table template according to different storage batteries; executing sequential control operations according to a sequential control table; configuring a control strategy template and a protection strategy template for different storage batteries, so as to guarantee the execution safety of each sequential control operation; building a discharge cut-off strategy template for different storage batteries, so as to calculate the discharge time and quantity which serve as the conditions for operation cut-off. The method effectively irons out the defects in the prior art, avoids accidents caused by errors which are caused by human factors, and achieves the automaton and intelligentization of a discharge process of storage batteries.
Description
Technical field: [0001] The invention relates to a one-key discharging method for a substation storage battery group, which belongs to the field of substation monitoring. Background technique: [0002] Long-term use of the floating charging operation mode with pressure and current limitation or the operation mode of only voltage limitation and no current limitation, it is impossible to judge the existing capacity of the VRLA battery and whether the interior is dehydrated or cracked. Only through the checking discharge test can the problems of the battery be found and the actual capacity and health level of the battery pack can be correctly evaluated. [0003] At present, the discharge process of maintenance personnel basically follows the following steps: [0004] 1. Check whether the busbar voltage of sections I and II is normal, check whether the DC load current is normal, and whether the busbar voltages of the two sections are consistent. According to these conditions, m...
