Description

Embodiments of the present invention relate to a start control device, a control method for a start control device, and a program.

Conventionally, emergency power generation equipment is known that, in automatic mode, can supply power to important loads through automatic control during a commercial grid outage.

Japanese Patent Application Publication No. 7-132000

However, conventional emergency power generation equipment is designed to be started unmanned, so even if someone is present around the power generation equipment (within a restricted area when the power generation equipment is running) during startup to perform an inspection, etc., there is no function to detect this state, and there is a risk that the emergency power generation equipment will be started.

Conversely, when the power generating equipment is in a power supply state due to a commercial grid blackout, if the operating mode is switched to manual mode, it is possible to turn off (shut off) the circuit breaker installed in the power supply path of the generating equipment, and there is a risk that power will not be supplied to important loads if this is done incorrectly.

The present invention has been made in consideration of the above problems, and aims to provide a start-up control device, a control method for a start-up control device, and a program that can ensure the safety of people when starting up an emergency power generation device, reliably supply power to important loads, and prevent erroneous operation by people when emergency power is being supplied.

The start-up control device of the embodiment includes a human presence sensor for detecting whether a person is entering a monitoring area corresponding to the controlled device, and a confirmation request unit that, when the human presence sensor detects that a person is entering the monitoring area around the control panel of the controlled device and a stop request is made in the control panel to effectively stop operation of the controlled device, displays a predetermined confirmation to request confirmation from an operator of the control panel of the control panel of the execution of the processing corresponding to the stop request.

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. FIG. 3 is a sequence flowchart for starting the generator. FIG. 4 is a sequence flowchart when the generated power is supplied.

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 the 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.

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 converts the extra-high voltage AC power supplied from the commercial power supply system CM and supplies it to the load.

The second power supply system 12 includes disconnectors DS21, DS22, and DS23 that open and close the electrical path between the commercial power supply system CM and the load, circuit breakers CB21, CB22, and CB23 that cut off the electrical path between the commercial power supply system CM and the load, and an extra-high voltage transformer HTR2 that converts the extra-high voltage AC power supplied from the commercial power supply system CM and supplies it to the load.

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 interrupt 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.

The power distribution system 14 includes circuit breakers CB41, CB42, and CB43 that cut off the corresponding electrical circuits, and circuit breakers CB51, CB52, ..., CB5x, CB5y, and CB5z that cut off the electrical circuits that supply power to the corresponding loads. In this case, x, y, and z are integers, and 2<x<y<z.

Circuit breaker CB51 and circuit breaker CB52 function as generator load circuit breakers and are circuit breakers corresponding to important load ILD that supplies power even during a power outage. Circuit breaker CB5x is a circuit breaker corresponding to normal load LDx, circuit breaker CB5y is a circuit breaker corresponding to normal load LDy, and circuit breaker CB5z is a circuit breaker corresponding to normal load LDz.

In the above configuration, the first power supply system 11 and the second power supply system 12 may be connected to a load at the same time to supply large amounts of power, or one of the power supply systems may supply power under normal circumstances, and if one of the power supply systems is unable to supply power due to a malfunction or the like, the other power supply system may supply power.

The controller 15 is configured as a so-called computer, and controls each part of the extra-high voltage substation 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.

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 a battery that stores 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.

In the above configuration, the surveillance cameras 27A and 27B are positioned so as to be able to monitor a first surveillance area AR1 set around the prime mover 21 and the generator GE, a second surveillance area AR2 set on the operation panel 25P side of the generator panel 25, and a specified surveillance area AR3 of the operation panel 25P.
In this case, the first monitoring area AR1 functions as a prohibited approach 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.

Prior to describing the operation of the embodiment, the basic concept of the embodiment will be described.
In this embodiment, a human presence sensor and a speaker serving as an alarm device are installed in the installation location (such as a generator room) of a generator GE, which is an emergency power generating device.
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).

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

In addition, during a power outage, when the generator GE is supplying generated power, the presence of a person is detected by a human presence sensor in the equipment operation area (within the second monitoring area AR2) and, if a switch to manual mode is performed, the circuit breakers CB31, CB32, CB51, and CB52 can be switched off 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 the switch with a display function provided on the generator panel 25, which serves as a control panel, assuming that a request for a stop operation has been made.

The controller, when operated by an operator (person) using a switch with a display function, checks whether the request for a stop operation has been made correctly before actually turning off (effectively stopping) the circuit breakers CB31, CB32, CB51, and CB52 installed in the generator's generated power supply system, thereby preventing erroneous operation.

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 conditions) 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.

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.) and detects the presence of people using the human presence sensor, and automatically starts the generator GE after the start preparation completion indicator lights up.

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.

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.

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.
When the operation mode in the controller 15 is automatic, the automatic mode signal SS2 goes to "H" level.
As a result, when the commercial power outage detection signal SS1 is at "H" level and the automatic mode signal SS2 is at "H" level, the controller 15 sets the power outage signal SS3 to "H" level.

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, and 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.

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 "H" level, the controller 15 sets the start operation signal SS6 to "H" level.

In parallel with the above operation, the controller 15 sets the start condition satisfaction signal SS8 to the "H" level when all of n start condition signals SS7-1 to SS7-n (n is an integer of 2 or more) that must be satisfied when starting the generator GE, such as "no equipment failure", ..., "no stop command", etc., are at the "H" level.

In addition, when the start mode is an alarm mode that issues an alarm if a person is present in a monitoring area corresponding to a specified no-approach area based on the output of the monitoring cameras 27A and 27B as human presence sensors, the controller 15 sets the alarm mode signal SS9 to "H" level and maintains that state until the start mode is changed.

Similarly, regardless of the output of the surveillance cameras 27A and 27B as human presence sensors, when the exclusion mode is set to start the generator GE, the controller 15 sets the exclusion mode signal SS10 to "H" level and maintains this state until the start mode is changed.

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 in a monitoring area corresponding to a specified no-approach area based on the output of the monitoring cameras 27A and 27B as human presence sensors, the lock mode signal SS11 is set to the "H" level.

As a result, the controller 15 takes the logical sum (OR) of the alarm 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 alarm 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 alarm mode signal SS9 is at the "L" level and the lock mode signal SS11 is at the "L" level.

In addition, based on the output of the surveillance cameras 27A and 27B as human presence sensors, if a person is detected within the first surveillance area AR1, which is an approach-prohibited area, the human detection signal SS13 is set to "H" level. This human detection signal SS13 is negated (NOT) by the controller 15, and becomes a human undetected signal SS14 that is set to "H" level if no person is detected within the first surveillance area AR1, which is an approach-prohibited area.

In addition, the controller 15 performs a logical AND operation on the alarm mode signal SS9 and the human detection signal SS13. 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 a danger/evacuation announcement (alarm) is issued by the alarm device 28.

In addition, the controller 15 takes the logical product (AND) of the start instruction signal SS12 and the non-human detection signal SS14, and when the start instruction signal SS12 is at the "H" level and the non-human detection 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.

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.

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.

In other words, when a power outage in the commercial power system is confirmed and the generator GE is ready to start, a start signal SS21 is output to the generator panel 25 to prompt the generator GE to start in order to start the generator and supply power to important loads.

As a result, the generator panel 25 starts driving the prime mover 21, which starts driving the generator GE and generates 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 the 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.

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

Furthermore, when a person is detected within the second monitoring area AR2, which is the device operation area, based on the output of the monitoring cameras 27A, 27B as human sensors, the human detection signal SS34 is set to "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.

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 (flashing 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 (turns on) 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 off the circuit breaker CB31, which functions as a generator circuit breaker, (to a cut-off state), the first circuit breaker switching operation signal SS37 is set to the "H" level.

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

Similarly, if a cut-off operation is performed on the generator panel 25 to turn off the circuit breaker CB32, which functions as a generator connection circuit breaker, (to a cut-off state) in parallel with the above operation, the second circuit breaker cut-off operation signal SS40 is set to the "H" level.

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

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

In addition, if a switching operation to switch circuit breakers CB51 and CB52 off (disconnected state) is performed in parallel with the above operation on the generator panel 25, the third circuit breaker switching operation signal SS45 is set to the "H" level.

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

In the same manner, the controller 15 performs a logical AND operation on the flicker stop signal SS36, the second circuit breaker off operation signal SS40, and the second circuit breaker status signal SS42. 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 "H" level, that is, when the circuit breaker CB32 is in the on state and the circuit breaker CB32 is turned off in the generator panel 25, and the flicker state of the commercial power outage caution lamp is stopped, the controller 15 sets the second circuit breaker off control signal SS47 to "H" level, causing the generator panel 25 to turn off the circuit breaker CB32.

In the same manner, the controller 15 performs a logical AND operation on the flicker stop signal SS36, the third circuit breaker off operation signal SS45, and the third circuit breaker status signal SS44. 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 "H" level, that is, when the circuit breakers CB51 and CB52 are in the on state and 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 is stopped, the controller 15 sets the second circuit breaker off control signal SS47 to "H" level and causes the generator panel 25 to turn off the circuit breakers CB51 and CB52.

To summarize the above, even if the circuit breaker CB31, circuit breaker CB32, or circuit breakers CB51 and CB52 is turned off, the corresponding circuit breaker is not immediately turned off, but the commercial power outage warning lamp is made to flicker to allow the operator to confirm whether or not the operation was intended, and the flickering of the commercial power outage warning lamp is stopped, so that the operator's intention is confirmed before the corresponding circuit breaker is turned off.
Therefore, when the generator GE is in a power supplying state, the risk of power supply to important loads being erroneously cut off can be reduced, and the supply of emergency power can be continued more reliably.

In the above explanation, we have described the case where surveillance cameras 27A, 27B are used as human presence sensors, but human presence sensors can be similarly applied as long as they are sensors that can confirm the presence of people such as workers, including optical sensors such as laser sensors and infrared sensors, and sound wave sensors such as ultrasonic sensors.
It is preferable to use a surveillance camera to monitor the operating state of the operation section of the generator panel 25 and the display state of the display section.

In the above explanation, a commercial power outage warning lamp was 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.

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.

The program executed by the controller 15 of this embodiment can also be configured to be provided in an installable or executable format file recorded 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).

The program executed by the controller 15 of this embodiment may be stored on a computer connected to a network such as the Internet and provided by downloading it via the network.
