- each substation has a number and a structural organization of cut-offs of its own and generally different from other electrical substations.
- the number of maintenance operations defined for each substation can vary considerably from one station to another. From the point of view of the optimized maintenance system 12, it is furthermore irrelevant whether a maintenance operation involves a part of an electrical substation, an entire electrical substation, several parts of substations, or even why not several entire substations.

- the memory 42 includes in particular a space for recording and storing information on maintenance operations to be performed.
- a first maintenance operation M1 generally a maintenance operation to be performed periodically on a set of cut-off devices, is completely defined by:
- each maintenance operation Mi a sequential list 48, of successive maneuvers of openings and closures to be automatically executed on the cut-off devices concerned by this maintenance operation Mi, at least one possible time window of execution indicated in a corresponding file 50, and a set 52, of execution requirements.

- the computer 46 can receive real-time weather information from outside by the interface 44.
- the computer 46 comprises, for example in the form of computer programs, the following functional elements:
- this selection module is programmed to make its selection according to the information available in memory 42 on each operation of maintenance to be performed, depending optionally on available weather information and on the basis of an impact result that the simulator 56 can provide on each of these operations as defined, in the predetermined time window,
- control unit 60 configured for a sequential placement of maintenance operations selected by the module 58 in the predetermined time window, and for a triggering of each maintenance operation selected at the required time by sending a command to this effect to the relevant enforcement system.
- the simulator 56 is, for example, compliant with the Convergence software platform developed by "RTE Transmission Network", or similar. Part 6.6 of the European Network of Transmission System Operators for Electricity (ENTSOE) document entitled “Interoperability test” CIM for System Development and Operations ", final version of 15 August 201 1, describes the main technical features of this software platform.
- Such a tool is capable of anticipating, in a chosen time window, the impact of local cuts and / or malfunctions on a general operation of the network 10. It is therefore capable of simulating the impact of a given maintenance operation Mi in the predetermined time window chosen.
- it is capable of performing calculations in static and dynamic modes.
- the selection module 58 is itself programmed to select some of the maintenance operations to be performed in the predetermined time window. It is therefore advantageously designed not to select a maintenance operation Mi whose time information of possible executions defined in the corresponding file 50 does not intersect with the predetermined time window. A pre-selection can be done on this basis to limit the maintenance operations whose impact is to simulate. It is also optionally advantageously designed to take into account priorities in the maintenance operations to be performed, these priorities may also change over time.
- the computer 46 may itself be programmed to execute the selection module 58 and the control unit 60 successively on a regular basis, in particular every working day under the supervision of an operator, or even possibly every day throughout the year for at least partially autonomous operation.
- the predetermined time window indicated above can be set to begin after execution of the selection module 58 and the control unit 60 and to stop before the end of the day.
- the computer 46 is designed to execute the simulator 56 during an execution of the control unit 60 so as to regularly simulate the impact of each maintenance operation selected and placed in the control unit. predetermined time window on a current state of the network 10 until the scheduled time for its execution.

- the functions performed by the aforementioned programs could be at least partially micro programmed or micro wired in dedicated integrated circuits.
- the computer device implementing the computer 46 of the processing unit 40 could be replaced by an electronic device composed solely of digital circuits (without a computer program) for performing the same functions.
- FIG. 1 is in a manner known per se managed by at least one remote monitoring site connected to each of the substations 16, 18, 20, 22, the optimized maintenance system 12 can be implemented in one of these remote sites. Alternatively, it could also be installed inside one of the substations 16, 18, 20, 22.
- n maintenance operations M1, Mi, Mn for example each relating to the cut-off members to be periodically maneuvered, are defined, recorded by an operator and stored in memory 42.
- Each maintenance operation Mi is for example defined by:
- this information feeds the sequential list 48, - a wide execution period: it can comprise several possible execution time windows indicated in the file 50, prerequisites 52, in the form of a local operating diagram of the network 10: topologies, load reports, production agreements that are suitable for carrying out the maintenance operation in question and that must be taken into account before and / or after this execution ,
- prerequisites 52 in the form of execution preparation constraints: in particular customers, maintenance personnel, neighboring network operators, production centers to contact or with whom to coordinate,
- prerequisites 52 in the form of operating restrictions: damage, degraded modes or material specificities of the devices and cut-off devices concerned by the maintenance operation in question, in terms of maneuvers or temporality; diagrams specific to live work that may prohibit certain maneuvers,
- each maintenance operation may be an occurrence of a more general maintenance operation to be performed periodically, for example annually, semi-annually or otherwise.
- the computer 46 defines a time window for executing maintenance operations.
- this window can be predefined for the next twenty-four hours, in a slot of several hours of the day in question (for example: [05:00, 19:00]), etc.
- it can also be defined by interaction between an operator and the computer 46. It must be completed before being executed again at a subsequent occurrence.
- the computer 46 executes the selection module 58 during a step 104.
- This step 104 itself comprises a first substep 106 of preselection of a first part of the maintenance operations to be executed stored in memory 42.
- This preselection 106 can be done by retaining only the maintenance operations of which the wide execution period indicated in the file 50, intersects with the predetermined time window in step 102. It can also be done by considering a maximum number of maintenance operations to be performed in the predetermined time window and / or priority rules such as: favoring the operations of maintenance with a reduced running time, prioritize maintenance operations that are considered difficult, etc.
- This preselection 106 can also be done considering constraints such as: unavailability of some maintenance operators essential to the performance of certain maintenance operations, avoid multiplying in the predetermined time window maintenance operations requesting each of the maintenance operators in the same neighborhood, for example on the same electrical station, temporarily unfavorable weather conditions for certain maintenance operations, withdrawals of power lines or specific operations planned or indicated by tele-information in the predetermined time window, etc.
- the preselection sub-step 106 can be defined on the basis of rules as numerous and precise as desired, the consideration of these rules can then be managed with the aid of a conventional expert system which will not be detailed. It results in the provision of a preselection of maintenance operations to be performed in the predetermined time window with, possibly, an order of priority.
- Step 104 includes a second substep 108 of enabling the ability to execute each preselected maintenance operation in the predetermined time window.
- this validation 108 can be done by verifying that there is no prohibited maneuver preventing the execution of at least one of the preselected maintenance operations in the predetermined time window. It can also be done by checking that there is no effervescence in the network 10 in a neighborhood more or less close, to be defined, each of the preselected maintenance operations. It can also be done by verifying that the prerequisites of each of the preselected maintenance operations are achievable in the predetermined time window.
- This simulation is generally done by executing the simulator 56 on each maintenance operation preselected in static mode in the predetermined time window and verifying that this simulation does not give rise to a failure in the network 10.
- This simulation is for example carried out in the form of an N-1 test, that is to say a test in which the unavailability of a transmission line is taken into account at the end of the maintenance operation considered.
- a test 1 10 is performed on the simulated impact of this operation. If a failure of the network 10 is generated by simulation throughout the predetermined time window, the maintenance operation in question is suppressed during a substep 1 12. If no failure of the network 10 is generated by simulation in the window predetermined time, the maintenance operation considered is validated during a sub-step 1 14. It can also be decided on a limit time H min (for example 16:00 if the predetermined time window is [05:00, 19:00]) in below which if a failure is generated by simulation at a time H 0 , the maintenance operation considered in the substep 1 14 is still valid, but for execution in a reduced time slot at] H 0 ; Hmin]. On the other hand, if a failure is generated by simulation at a time greater than or equal to H min , the operation is suppressed in substep 1 12.
- H min for example 16:00 if the predetermined time window is [05:00, 19:00]
- the substeps 1 12 and 1 14 are followed by a substep 1 16 during which it is tested whether all the preselected maintenance operations have been processed by the simulator 56. If no, we return to the substep If yes, the method proceeds to a step 1 18 of sequential placement and triggering of the maintenance operations validated in step 104.
- Step 1 18 is performed by execution, by the computer 46, of the control unit 60.
- This step 1 18 itself comprises a first substep 120 sequential placement of each maintenance operation in the predetermined time window.
- This sequential placement 120 can be done taking into account priorities and imposing a minimum time spacing (for example 30 minutes) between two successive maintenance operations when they are located in the same neighborhood to be defined.
- This investment can also be done in working or non-business hours, according to availability criteria close to emergency response teams, depending on the nature of the cut-off devices concerned (for example: prioritize maintenance operations without disconnector in non-working hours), etc.
- the sequential placement substep 120 can be defined on the basis of rules as numerous and precise as desired, the consideration of these rules can then be managed using a conventional expert system that will not not detailed. It results in a sequence of maintenance operations to be performed in the predetermined time window.
- step 122 triggering the validated maintenance operations and placed temporally. For each validated and placed operation, this step 122 requests the simulator 56 in dynamic mode on a regular basis until the scheduled time for its execution. It cancels the maintenance operation considered as soon as the conditions of its selection, by simulation at the scheduled time for its execution, are no longer verified. It also triggers, if necessary and for each maintenance operation validated and placed to execute, a step 124 of generating a preparation sheet of the maintenance operation, a step 126 of sending a command of performing the maintenance operation at the execution device concerned and a step 128 of generating a report card of the maintenance operation once executed.
- the step 124 is for example triggered for a maintenance operation a few hours (for example between one and three hours) before the scheduled time of its execution. It consists in presenting to a man-machine interface of the optimized maintenance system 12 a description of the maintenance operation that will be executed. It allows an operator to act to cancel or suspend the operation himself and informs him of any actions to be taken upstream so that the conditions for its execution are verified.
- step 126 is followed, once it is actually executed for one of the validated and placed maintenance operations, of a deletion of the maintenance operation in question (or of its considered occurrence). it is a periodic maintenance operation) in the list of maintenance operations to be executed stored in memory 42.
- step 128 is triggered a few seconds after the actual execution of a maintenance operation. It consists in presenting to a man-machine interface of the optimized maintenance system 12 a description of the maintenance operation that has just been executed. It reports on the good or bad performance of the maintenance operation, its possible consequences on the network 10. It can also inform an operator of actions to be carried out following its execution, whether as a result of a success or a failure of this execution. In the event of failure, the maintenance operations programmed subsequently in the predetermined time window may be suspended for the day and / or on the zone in question (as a grouping zone of substations), except possibly if the system has information that failure can be quickly overcome and other planned maintenance operations are resumed.
- the process returns to step 102 for a new successive execution of steps 104 and 1 18 during a new time window.
