Industry Background

Solution Overview

The substation maintenance safety management and control system enhances the locking and control functions for substation maintenance, and adds mandatory interlocking for secondary safety measures, maintenance topology verification, pre-test directed authorization, and online equipment status verification. It also integrates the maintenance workflow with existing anti-misoperation devices/systems to establish a comprehensive safety management system for the entire maintenance process, including safety measure deployment, operation control of safety measure devices, maintenance equipment drive operation, safety measure removal, and equipment status comparison, improving the production safety level of substation maintenance.

Solution Advantages

Mandatory deployment of secondary safety measures

Mandatory deployment of secondary safety measures

Different types of locking methods are applied to secondary equipment such as hard clamps, secondary circuit breakers, operation handles, and trip/close buttons.

Custom maintenance rules

Custom maintenance rules

The system supports three modes: single equipment maintenance, area equipment maintenance, and full-site equipment maintenance. It provides corresponding maintenance logic based on equipment type and connection relationships, allowing only equipment that meets maintenance logic to be included in the maintenance task during ticket creation.

Pre-test/drive directed authorization

Pre-test/drive directed authorization

During on-site testing of maintenance equipment, the system determines whether the equipment is authorized using maintenance keys. If yes, on-site operation testing is allowed; if not, operation is prohibited. During remote drive operations, only authorized maintenance equipment can be remotely operated; otherwise, operation is prohibited.

Online status comparison

Online status comparison

The system records equipment status before and after maintenance, automatically comparing the collected status information and issuing alarms if discrepancies are found.
