[0009] Next, the embodiments will be described in detail with reference to the drawings. FIG. 1 is a single-line diagram of a special high voltage substation system to which an embodiment is applied. The extra-high voltage substation system 10 includes a first power supply system 11, a second power supply system 12, a generated power supply system 13, a power distribution system 14, and a controller 15 that controls the entire extra-high voltage substation system 10.

[0010] The first power supply system 11 includes circuit breakers DS11, DS12, and DS13 that open and close the electrical path between the commercial power supply system CM and the load, circuit breakers CB11, CB12, and CB13 that interrupt the electrical path between the commercial power supply system CM and the load, and an extra-high voltage transformer HTR1 that performs power conversion on the extra-high voltage AC power supplied from the commercial power supply system CM and supplies it to the load side.

[0011] The second power supply system 12 includes circuit breakers DS21, DS22, DS23 that open and close the electric path between the commercial power supply system CM and the load, circuit breakers CB21, CB22, CB23 that interrupt the electric path between the commercial power supply system CM and the load, and an extra-high voltage transformer HTR2 that performs power conversion on the extra-high voltage AC power supplied from the commercial power supply system CM and supplies it to the load side.

[0012] The generated power supply system 13 includes a generator GE that is driven by a heat engine such as a prime mover to generate power, circuit breakers CB31 and CB32 that break the electrical path between the generator GE and a load, and a cable CBL. In this case, the circuit breaker CB31 functions as a generator circuit breaker, and the circuit breaker CB32 functions as a generator connection circuit breaker.

[0013] The power distribution system 14 includes circuit breakers CB41, CB42, and CB43 that interrupt the corresponding electric circuits, and circuit breakers CB51, CB52, ..., CB5x, CB5y, and CB5z that interrupt the electric circuits that supply power to the corresponding loads. In this case, x, y, and z are integers, and 2 <x<y<zとなっている。

[0014] Circuit breaker CB51 and circuit breaker CB52 function as generator load circuit breakers and correspond to important load ILD that supplies power even during a power outage. Circuit breaker CB5x corresponds to normal load LDx, circuit breaker CB5y corresponds to normal load LDy, and circuit breaker CB5z corresponds to normal load LDz.

[0015] In the above configuration, the first power supply system 11 and the second power supply system 12 may be connected to a load simultaneously to supply large power, or one of the power supply systems may supply power under normal circumstances, and when one of the power supply systems is unable to supply power due to a failure or the like, the other power supply system may supply power.

[0016] The controller 15 is configured as a so-called computer, and controls each part of the extra-high voltage receiving and transforming system 10 based on a pre-stored program, and functions as a start / stop alarm part, a release part, and a confirmation request part. The controller 15 also functions as a so-called sequencer.

[0017] FIG. 2 is a plan view of an example of a power generating room in which a generator constituting a generated power supply system is disposed. Within the generating room 20 are a generator GE, a prime mover 21 as a heat engine for driving the generator GE, an exhaust pipe 22 equipped with a silencer 22A for silencing noise generated when the prime mover 21 is in operation, a fuel tank 23 for storing fuel for driving the prime mover 21, auxiliary machinery 24, a generator panel 25 equipped with controls for operating the generator GE and various display devices, etc., a battery panel 26 for controlling the storage battery that stores the electricity generated by the generator GE, surveillance cameras 27A, 27B as human presence sensors, and an alarm device 28 that outputs an alarm by voice.

[0018] In the above configuration, the surveillance cameras 27A and 27B are positioned so as to be able to monitor a first monitoring area AR1 set around the prime mover 21 and the generator GE, a second monitoring area AR2 set on the operation panel 25P side of the generator panel 25, and a specified monitoring area AR3 of the operation panel 25P. In this case, the first monitoring area AR1 functions as an access restriction area that prohibits people from approaching when the generator GE is running, and the second monitoring area functions as an equipment operation area where the generator GE is operated.

[0019] Prior to describing the operation of the embodiment, the basic concept of the embodiment will be described. In this embodiment, a human sensor and a speaker serving as an alarm device are installed in a location (such as a generator room) where a generator GE, which is an emergency power generating device, is installed. In this case, a human presence sensor is installed at the installation location of the emergency power generation device so as to be able to determine the presence or absence of people in the no-approach area (first monitoring area AR1) and the equipment operation area (second monitoring area AR2).

[0020] In this embodiment, if a human presence is detected by a human presence sensor in the no-approach area (first monitoring area AR1) during a commercial power outage, an announcement such as "Danger - Evacuate" is made, and after it is confirmed that the people have evacuated, automatic control is continued, thereby ensuring the safety of people while supplying power to the important load ILD.

[0021] In addition, during a power outage while the generator GE is supplying generated power, a human presence is detected by a human sensor within the equipment operation area (within the second monitoring area AR2) and, if an operation to switch to manual mode is performed, it becomes possible to turn off the circuit breakers CB31, CB32, CB51, and CB52 to effectively stop the operation of the generator GE, which is the controlled device, and the controller 15 functions as a confirmation request unit and flickers a switch with a display function provided on the generator panel 25, which serves as a control panel, as a request for a stop operation.

[0022] When an operator (person) operates the switch with a display function, the controller verifies the operator's intention as to whether the request for a stop operation has been made correctly before actually performing an "off" operation (effective shutdown operation) on the circuit breakers CB31, CB32, CB51, and CB52 installed in the generator's generated power supply system, thereby preventing erroneous operation.

[0023] Furthermore, in this embodiment, different types of alarms and controls are used after the human presence is detected by the human presence sensor depending on the setting of the start mode (processing condition) in the monitoring area (first monitoring area AR1) corresponding to a specified no-approach area. Specifically, in the following description, it is assumed that the start mode includes a warning mode, an exclusion mode, and a lock mode.

[0024] The alarm mode is a start mode that announces "Danger - Evacuate" when people can easily evacuate from the no-approach area (by visual inspection, etc.) or when the presence of a person is detected by the human sensor, and automatically starts the generator GE after the start preparation completion indicator lights up.

[0025] The exclusion mode is a start mode in which the generator GE is automatically started regardless of the detection state of the human presence sensor. The lock mode is a start-up mode that prohibits the generator GE from starting while a human presence is detected by a human presence sensor in a monitoring area corresponding to a specified no-approach area, and automatically starts the generator GE when the human presence is no longer detected by the human presence sensor.

[0026] As a result, people's safety can be ensured. In addition, after the generator starts, if it is in manual mode, it is possible to turn off the circuit breaker, which could result in the important load being stopped. However, in this case, when the circuit breaker is turned off, it is treated as a stop request, and the execution of the processing corresponding to the stop request is confirmed before the actual stop processing is performed, thereby making it possible to prevent erroneous operation.

[0027] Next, the operation of the embodiment will be described. FIG. 3 is a sequence flowchart for starting the generator. When the controller 15 detects a power outage in the commercial power system, the commercial power outage detection signal SS1 goes to the "H" level. Moreover, when the operation mode in the controller 15 is automatic, the automatic mode signal SS2 goes to the "H" level. As a result, when the commercial power outage detection signal SS1 is at the "H" level and the automatic mode signal SS2 is at the "H" level, the controller 15 sets the power outage signal SS3 to the "H" level.

[0028] Furthermore, when a predetermined time has elapsed since the power failure signal SS3 at "H" level was output, the power failure confirmation signal SS4 goes to "H" level. The reason why the power outage signal SS3 at "H" level is not used for direct control, but the power outage confirmation signal SS4 is set to "H" level after a predetermined time has elapsed, is to suppress the effects of temporary voltage fluctuations, etc., and to reliably detect power outages.

[0029] On the other hand, when the operation mode is manual, in order to start the generator, the push button switch is operated to set the start operation signal SS5 to "H" level. As a result, when either the power failure confirmation signal SS4 or the start operation signal SS5 goes to the "H" level, the controller 15 sets the start start signal SS6 to the "H" level.

[0030] In parallel with the above operation, the controller 15 sets the start condition satisfaction signal SS8 to the “H” level when all of n (n is an integer greater than or equal to 2) start condition signals SS7-1 to SS7-n, which indicate a number of conditions that must be satisfied when starting the generator GE, such as “no equipment failure”, ..., “no stop command”, etc., are at the “H” level.

[0031] In addition, when the start mode is an alarm mode in which an alarm is issued when a person is present in a monitoring area corresponding to a predetermined no-approach area based on the output of the surveillance cameras 27A, 27B as human presence sensors, the controller 15 sets the alarm mode signal SS9 to the “H” level and maintains that state until the start mode is changed.

[0032] Similarly, regardless of the output of the surveillance cameras 27A, 27B as human presence sensors, when the exclusion mode is selected to start the generator GE, the controller 15 sets the exclusion mode signal SS10 to the “H” level and maintains that state until the start mode is changed.

[0033] In addition, when the start mode is a lock mode in which the start of the generator GE is (temporarily) suppressed when a person is present within a monitoring area corresponding to a specified no-approach area based on the output of the surveillance cameras 27A, 27B as human presence sensors, the lock mode signal SS11 is set to the “H” level.

[0034] As a result, the controller 15 takes the logical sum (OR) of the warning mode signal SS9 and the lock mode signal SS11, and then takes a negation (NOT) and sets the start instruction signal SS12 to the "L" level if the warning mode signal SS9 is at the "H" level or the lock mode signal SS11 is at the "H" level. In other words, the start instruction signal SS12 is set to the "H" level only when the warning mode signal SS9 is at the "L" level and the lock mode signal SS11 is at the "L" level.

[0035] Furthermore, when a person is detected in the first monitoring area AR1, which is an approach-prohibited area, based on the output of the monitoring cameras 27A and 27B as human presence sensors, the human detection signal SS13 is set to the "H" level. This human detection signal SS13 is negated (NOT) by the controller 15 to become a human undetected signal SS14, which is set to the "H" level when no person is detected in the first monitoring area AR1, which is an approach-prohibited area.

[0036] In addition, the controller 15 takes the logical product (AND) of the alarm mode signal SS9 and the human detection signal SS13, and when the alarm mode signal SS9 is at the “H” level and the human detection signal SS13 is at the “H” level, this indicates that a person is present in the first monitoring area AR1, which is a no-approach area, and so a danger / evacuation announcement (alarm) is issued by the alarm device 28.

[0037] In addition, the controller 15 takes the logical product (AND) of the start instruction signal SS12 and the undetected human signal SS14, and when the start instruction signal SS12 is at the "H" level and the undetected human signal SS14 is at the "H" level, the controller 15 sets the start instruction confirmation signal SS16 to the "H" level. As a result, the controller 15 takes the logical sum (OR) of the exclusion mode signal SS10 and the start instruction confirmation signal SS16, and sets the start command signal SS17 to the “H” level when the exclusion mode signal SS10 is at the “H” level or when the start instruction confirmation signal SS16 is at the “H” level.

[0038] As a result, the controller 15 takes the logical product (AND) of the start condition satisfaction signal SS8 and the start command signal SS17, and when the start condition satisfaction signal SS8 is at the “H” level and the start command signal SS17 is at the “H” level, the controller 15 sets the start preparation start signal SS18 to the “H” level. Then, when the predetermined start preparation is completed, the controller 15 sets the start preparation completion signal SS19 to the "H" level.

[0039] As a result, the controller 15 takes the logical product (AND) of the start-up signal SS6 and the start-preparation complete signal SS19, and when the start-up signal SS6 is at the “H” level and the start-preparation complete signal SS19 is at the “H” level, it outputs a start permission signal SS20 and outputs a start signal SS21 to the generator panel 25.

[0040] In other words, when a power outage in the commercial power system is confirmed and preparations for starting the generator GE are complete, a start signal SS21 is output to the generator panel 25 to prompt the starting of the generator GE in order to start the generator GE and supply generator power to important loads.

[0041] As a result, the generator panel 25 starts driving the prime mover 21, which starts driving the generator GE, thereby generating electricity. Then, when the voltage of the generator GE is established at a predetermined voltage, the generator panel 25 outputs a first circuit breaker control signal SS22 to the circuit breaker CB31, which is a generator circuit breaker, to bring the circuit breaker CB31 into a closed state (on state). As a result, the generator GE is able to supply generated power.

[0042] Next, the operation when the generated power is supplied will be described. FIG. 4 is a sequence flowchart for supplying generated power. During a power outage when the power outage confirmation signal SS4 is at "H" level, the commercial power outage signal SS31 becomes "H" level, and is negated (NOT) by the controller 15 to become the commercial non-power outage signal SS32, which becomes "L" level during the power outage. When the operation mode is manual, a manual mode signal SS33 that goes to "H" level is output.

[0043] Furthermore, when a person is detected within the second monitoring area AR2, which is the device operation area, based on the outputs of the monitoring cameras 27A and 27B as human sensors, the human detection signal SS34 is set to the "H" level. As a result, the controller 15 takes the logical product of the commercial power outage signal SS31, the manual mode signal SS33, and the human detection signal SS34, and outputs a flicker instruction signal SS35 to the generator panel 25 to cause the commercial power outage warning lamp, which serves as a switch with a display function, to flicker.

[0044] When a flicker instruction signal SS35 is input from the controller 15 to the generator panel 25, the commercial power outage warning lamp on the generator panel 25 goes into a flickering state (blinking state), but by operating (pressing) the push button formed integrally with the commercial power outage warning lamp corresponding to the commercial power outage warning lamp, the flickering state stops (goes into a lit state) and the flicker stop signal SS36 goes to the “H” level. In addition, in parallel with the above operation, when a switching operation is performed on the generator panel 25 to switch the circuit breaker CB31, which functions as a generator circuit breaker, to the off state (interrupted state), the first circuit breaker switching operation signal SS37 is set to the “H” level.

[0045] In parallel with the above operation, when the circuit breaker CB31 is turned on (conducting state), the first circuit breaker on signal SS38 becomes the "H" level and is in the set state, the on state of the circuit breaker CB31 is stored, and the first circuit breaker status signal SS39 becomes the "H" level. When the commercial uninterrupted power signal SS32 becomes the "H" level, that is, in an uninterrupted power state, this first circuit breaker status signal SS39 is reset to the "L" level. In other words, in an uninterrupted power state, the first circuit breaker status signal SS39 is always maintained at the "L" level.

[0046] Similarly, when a switching operation is performed in the generator panel 25 to switch the circuit breaker CB32, which functions as a generator connection circuit breaker, to the off state (interrupted state) in parallel with the above operation, the second circuit breaker switching operation signal SS40 is set to the “H” level.

[0047] In parallel with the above operation, when the circuit breaker CB32 is turned on (conducting state), the second circuit breaker on signal SS41 becomes the "H" level and is in a set state, the on state of the circuit breaker CB32 is stored, and the second circuit breaker status signal SS42 becomes the "H" level. When the commercial uninterrupted power signal SS32 becomes the "H" level, that is, in an uninterrupted power state, the second circuit breaker status signal SS42 is reset to the "L" level. In other words, in an uninterrupted power state, the second circuit breaker status signal SS42 is always maintained at the "L" level.

[0048] In addition, in parallel with the above operation, when the circuit breakers CB51, CB52 functioning as generator load circuit breakers are turned on (conducting state), the third circuit breaker on signal SS43 becomes the "H" level and is in the set state, the on state of the circuit breakers CB51, CB52 is stored, and the third circuit breaker status signal SS44 becomes the "H" level. When the commercial non-power interruption signal SS32 becomes the "H" level, that is, in a non-power interruption state, this third circuit breaker status signal SS44 is reset to the "L" level. In other words, in a non-power interruption state, the third circuit breaker status signal SS44 is always maintained at the "L" level.

[0049] Furthermore, in parallel with the above operation, when a switching operation for switching off the circuit breakers CB51, CB52 (cutoff state) is performed on the generator panel 25, the third circuit breaker switching signal SS45 is set to the "H" level.

[0050] As a result of these, the controller 15 takes the logical product of the flicker stop signal SS36, the first circuit breaker off operation signal SS37, and the first circuit breaker status signal SS39, and if the flicker stop signal SS36, the first circuit breaker off operation signal SS37, and the first circuit breaker status signal SS39 are all at the "H" level, that is, when the circuit breaker CB31 is in the on state, the circuit breaker CB31 is turned off in the generator panel 25, and the flicker state of the commercial power outage caution lamp has stopped, the controller 15 sets the first circuit breaker off control signal SS46 to the "H" level, causing the generator panel 25 to turn off the circuit breaker CB31.

[0051] Similarly, the controller 15 takes the logical product of the flicker stop signal SS36, the second circuit breaker off operation signal SS40, and the second circuit breaker status signal SS42, and when the flicker stop signal SS36, the second circuit breaker off operation signal SS40, and the second circuit breaker status signal SS42 are all at the "H" level, that is, when the circuit breaker CB32 is in the on state, the circuit breaker CB32 is turned off in the generator panel 25, and the flicker state of the commercial power outage caution lamp has stopped, the controller 15 sets the second circuit breaker off control signal SS47 to the "H" level, causing the generator panel 25 to turn off the circuit breaker CB32.

[0052] Similarly, the controller 15 takes the logical product of the flicker stop signal SS36, the third circuit breaker off operation signal SS45, and the third circuit breaker status signal SS44, and when the flicker stop signal SS36, the third circuit breaker off operation signal SS45, and the third circuit breaker status signal SS44 are all at the "H" level, that is, when the circuit breakers CB51 and CB52 are in the on state, the circuit breakers CB51 and CB52 are turned off in the generator panel 25, and the flicker state of the commercial power outage caution lamp has been stopped, the controller 15 sets the second circuit breaker off control signal SS47 to the "H" level, causing the generator panel 25 to turn off the circuit breakers CB51 and CB52.

[0053] In summary, even when a cut-off operation is performed on circuit breaker CB31, circuit breaker CB32, or circuit breakers CB51 and CB52, the corresponding circuit breaker is not immediately cut off, but the Commercial Power Outage Caution lamp is made to flicker to allow the operator to confirm whether or not the operation was intended. The flickering of the Commercial Power Outage Caution lamp is stopped, and control is performed so that the corresponding circuit breaker is cut off only after the operator's intention is confirmed. Therefore, when the generator GE is in a power supply state, the risk of erroneously cutting off the power supply to important loads can be reduced, and the supply of emergency power can be continued more reliably.

[0054] In the above explanation, the surveillance cameras 27A, 27B are used as human presence sensors, but other types of human presence sensors can be used as well, including optical sensors such as laser sensors and infrared sensors, and sound wave sensors such as ultrasonic sensors, as long as they are capable of confirming the presence of people such as workers. It is preferable to use a surveillance camera to monitor the operating state of the operation section in the generator panel 25 and the display state of the display section.

[0055] In the above explanation, a commercial power outage caution lamp is used as a switch with a display function, but this is not limited to this. When a request for a stop operation is made to the controller 15 functioning as a confirmation request unit, a specified confirmation display may be made by turning on a specified lamp or outputting text on a display, and when confirmation is made using a specified operator (switch, touch panel, etc.), the stop operation (breaker shutoff operation) may be executed.

[0056] The controller (sequencer) 15 of this embodiment is equipped with a control device such as a CPU, a storage device such as a ROM (Read Only Memory) or RAM, and an external storage device such as a HDD or CD drive, and has a hardware configuration that utilizes a normal computer.

[0057] The program executed by the controller 15 of this embodiment can also be configured to be provided by being recorded in an installable or executable format on a computer-readable recording medium such as a CD-ROM, a semiconductor memory device such as a USB memory, or a DVD (Digital Versatile Disk).

[0058] The program executed by the controller 15 of the present embodiment may be stored in a computer connected to a network such as the Internet and provided by being downloaded via the network. The program executed by the controller 15 of the present embodiment may be provided or distributed via a network such as the Internet.

[0059] The program for the controller 15 of this embodiment may be provided by being pre-installed in a ROM or the like.
