[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of substation equipment provided with an electronic control system for controlling and monitoring various substation equipment.

[0002]

2. Description of the Related Art In modern society, electric power is inextricably linked with human life, and power failure is often a problem. Therefore, the demand for stable power supply is expected to increase further in the future. On the other hand, in a power transmission system that supplies electric power, although sufficient protection measures have been taken with the progress of technology, when a failure occurs in a substation device, the influence on the electric power supply becomes extremely large. Therefore, it is required to further improve the reliability of the substation equipment.

The main equipment of such substation equipment is as follows:
Switchgear, transformers, etc. can be mentioned. Among them, the switchgear has recently been mainly gas insulated switchgear (GIS).
Is used. In this gas insulated switchgear, a high voltage charging part having a switch, a conductor and the like is housed inside a grounded metal container together with an insulating medium such as SF ₆ gas which has excellent insulating properties and extinguishing properties. This gas-insulated switchgear has a compact installation volume per KV / A and is excellent in environmental resistance. Therefore, it is necessary to strengthen the substation equipment as the land price rises and the power supply in urban areas increases. Currently, it is widely used in substation equipment in various places as a device that satisfies the need for conversion.

FIG. 6 is a plan view showing an example of such a gas insulated switchgear, and FIG. 7 is a single wire connection diagram corresponding to the gas insulated switchgear of FIG. That is, in this gas-insulated switchgear, as shown in FIGS. 5 and 6, the power transmission line is pulled in via the bushing 1, and the main bus 5 is connected to the main bus 5 via the disconnector 2, the circuit breaker 3a and the main bus disconnector 4a. It is connected.
This main bus 5 is connected to the transformer 6 via the main bus disconnector 4b and the circuit breaker 3b of the transformer line. In addition,
Reference numeral 7 in the figure denotes a field control panel for controlling and monitoring each substation device that constitutes the gas insulated switchgear, and is installed mainly for each line of the gas insulated switchgear.

FIG. 8 is a block diagram of a circuit breaker control circuit for controlling and monitoring the circuit breakers 3a and 3b as a part of the circuit in the field control panel 7 shown in FIG. This circuit breaker control circuit has a closing circuit, a tripping circuit, and an open phase detection circuit,
Of these, the closing circuit has a closing command input terminal 11, a changeover switch 12, and an impedance element 13 as main components.
And a closing coil 14a connected in parallel to the impedance element 13. In the figure, 15 and 16 are auxiliary switch contacts indicating the operating position of the circuit breaker main body, contacts of a gas density switch that is turned on when the gas pressure in the grounded metal container (tank) of the circuit breaker main body decreases, or the circuit breaker main body. The contact point of a hydraulic switch that is turned on when the hydraulic pressure of the hydraulic operating mechanism is low. These contacts have functions such as operation lock of the circuit breaker and prevention of connection of the command signal for a certain time or longer.

On the other hand, the trip circuit is composed of a trip command input terminal 19, an impedance element 10 and a trip coil 14b connected in series to the impedance element 10 as main components. The part surrounded by the chain double-dashed line in FIG. 8 is the part installed in the circuit breaker main body, and the other parts are housed in the field control panel 7.

Next, FIG. 9 is a view showing the external appearance of the field control panel 7 shown in FIG. In the case 21 of the site control panel 7, a simulated bus bar display 22, an operation switch 23, a changeover switch 24, an alarm display section 25, a relay relay 26 and the like are installed.

[0008]

Therefore, the field control panel 7 of FIG. 8 is provided with a closing circuit, a tripping circuit, and an open-phase detection circuit, and the gas-insulated switchgear itself has high reliability, but the gas-insulated switchgear has a high reliability. Various switch contacts and relay contacts are used as operation / control circuits for operating the switchgear. Therefore, the reliability of the switches and relays for operation and control has become a problem, and failures such as contact failure of contacts have occurred.

Actually, according to the failure investigation of the operation mechanism in the Electric Joint Research Group and the like, the majority of the failures are related to the electrical equipment and the control circuit, and about 70% of the electrical equipment failures are poor contact continuity. Is reported.

In particular, since the control circuit in the field control panel 7 shown in FIG. 8 cannot perform self-diagnosis of the circuit when the contact is off, even if a failure such as contact failure occurs, the failure is caused by the contact. It is often not discovered until the actual operation of the device corresponding to. However, as a practical problem, if a failure such as a contact failure occurs, it may lead to a serious accident in the gas insulated switchgear.

Further, in the control circuit shown in FIG. 8, wiring between the gas-insulated switchgear and the field control panel 7 and wiring between the field control panel 7 and the substation control room are parallel wiring by electric wires. Therefore, there is a problem that the amount of wiring becomes very large.
Further, even in the internal wiring of the field control panel 7 shown in FIG. 9, the wiring by the electric cable is mainly used, so that the field control panel 7 itself becomes large, and the width W, the depth D, and the height H of the case 21 become large. There is a problem that ends up.

[0012] In order to solve the problems of the control circuit composed of the contacts and relays as described above, reference is made to the literature (electronic operation circuit for GIS operation / control circuit, 1994 IEEJ Power Energy). In the category competition No. 651), etc., a method for improving reliability by digitizing contacts and relays and performing self-diagnosis of the circuit system has been proposed.

As shown in FIG. 4 of this document, several types of units and sequencer (PC) are provided. The configuration of the system that connects and is very complicated. Further, since there are many types of units, the number of parts increases, and the field control panel 7 itself becomes large.
Further, in the document, a specific range of application of computerization, redundancy as a computerization control system, a specific configuration method of a higher-level system such as a device monitoring system (maintenance support system) which is recently expanding its application, No relation between the host system and the computerized control system is suggested. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a substation facility that changes the transmission mode according to the importance of information and ensures high speed and reliability.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of substation equipment according to the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram showing an embodiment of the substation equipment according to the present invention.

In this substation equipment, a switchgear main circuit 30 composed of various switchgear including a circuit breaker,
The switchboard main circuit 30 is composed of a field control panel 40 as a computerized control system for controlling / monitoring various switchgear devices and outputting / displaying information, and a host system 50.

This switchgear main circuit 30 includes a circuit breaker 31,

.About.42c are provided.

The control unit 41a and the monitoring unit 4
Each of the information output display unit 41c and 1b includes a microcomputer and the like, and is configured to execute a predetermined process based on program data. on the other hand,
The drive units 42a to 42c individually drive the switching devices such as the circuit breaker 31, the disconnector 32, and the grounding device 33 as described above.
A power electronic circuit having a FET and the like and a sensor signal input section are provided.

Further, the field control panel 40 is provided with a first internal transmission path 43 and a second internal transmission path 44 for exchanging data between the various units 41a to 41c and the drive units 42a to 42c. There is.

The first internal transmission path 43 is a high-speed data channel composed of a parallel data bus, and has high-speed response information such as protection relay information (operation command) required to have a high-speed response and operation information of a circuit breaker. Is a transmission path for transmitting. The reason why such a transmission path 43 is adopted is that it takes several ms or more in the case of normal data transmission and is insufficient in the case of performing high-speed operation control like the circuit breaker 31. .

The first internal transmission path 43 may have a structure in which a plurality of printed wirings are simply provided on the substrate. On the other hand, the second internal transmission path 44 is controlled by program processing, and specifically, transmission of a parallel data bus or serial data bus controlled by a microcomputer incorporated in the output display unit 41c. It is a road.

Further, the host system 50 is connected to the site control panel 40 via the first external transmission line 51 and the second external transmission line 52, and it is necessary to operate and control the circuit breaker 31 urgently. , High-speed response information is classified into high-speed response information such as protection relay information requesting so-called high-speed response and operation information of circuit breaker 31 and normal information such as control information and maintenance / inspection information that does not require urgency. In the case of information, it has a function of transmitting using the first external transmission path 51, and transmitting information other than the high-speed response information to the field control panel 40 via the second external transmission path 52.

That is, the first external transmission path 51 is constructed so that bidirectional data transmission can be performed between the information output display unit 41c of the field control panel 40 and the host system 50, and the second external transmission path 51 is also provided. It is used to transmit control information, maintenance / inspection information, and the like that require less urgency than the path 52. Therefore, the first external transmission line 5
As 1, a fiber optic cable is used instead of an electric cable.

On the other hand, the second external transmission line 52 transmits high-speed response information such as protection relay information from the host system 50 and operation information of the circuit breaker, and transmits it to the first internal transmission line 43 of the field control panel 40. It is configured to be introduced. That is, the high-speed response information is the second external transmission line 5 directly connected to the parallel wiring.
2 through control unit 41a, monitoring unit 41b,
The information output display unit 41c and the breaker drive unit 42a can be simultaneously introduced.
In particular, the protection relay information from the host system 50 needs to drive the circuit breaker 31 urgently in the event of an accident, and therefore requires high reliability and high speed. Therefore, the second
The external transmission line 52 is composed of an electric cable in order to meet such a requirement.

Next, FIG. 2 is a diagram showing an example of the configuration of the transducer 34a attached to the circuit breaker 31. The transducer 34a includes a trip coil 61,
The closing coil 62, the position sensor 63, the hydraulic pump 64, the hydraulic pressure sensor 65, the gas density sensor 66, etc.
Among them, the trip coil 61, the closing coil 62 and the hydraulic pump 64 are the MOS in the drive unit 42a.
Connected to a power electronic circuit 42aa having a FET etc.,
The outputs of the position sensor 63, the hydraulic pressure sensor 65, and the gas density sensor 66 are introduced into the sensor signal input section 42ab in the drive unit 42a.

FIG. 3 is a view showing the external appearance of the site control panel 40 shown in FIG. In the case 45 of the site control panel 40, each unit 41 (41a to 41c), drive unit 42 (42a to 42c) and transducer 4 are provided.
6 is housed, and an operation display panel 47 is arranged on the front side inside the panel.

Next, the operation of the substation equipment constructed as described above will be described. Normally, when protecting the switchgear main circuit 30 in the event of an accident in a substation device, the circuit breaker 31 is based on the protection relay information during an extremely short time of the order of ms or less.
Must be driven. In addition, even when the circuit breaker 31 is actually driven, in the operation related to the anti-poping control or the control corresponding to the open phase protection,
It is necessary to perform the response with a response time of ms order or less based on the operation command and the information on the position corresponding to the on / off of the circuit breaker 31.

By the way, generally, in the field control panel 40 for electronic control using a microcomputer, a method of exchanging data across each unit through a bus is used. However, such a simple method includes the circuit breaker 31 as it is. When applied to the control of various switchgear, it is not possible to sufficiently deal with the required high-speed response.

Therefore, as a means for overcoming the above problems, as shown in FIG. 1, the second external transmission line 5 capable of high-speed transmission of the high-speed response information regarding the circuit breaker 31 and the like.
2 and the first internal transmission line 4 which is a parallel data bus
3, the field control panel 40, in particular, receives the high-speed response information and individually transmits the parallel lines of the first internal transmission path 43 to each of the units 41a to 41c, 42.
This is a system that is introduced into a simultaneously.

As described above, since the first internal transmission path 43 is used for data transmission by parallel wiring, it is expected that the first internal transmission path 43 will be disadvantageous in terms of system cost, size and the like. In order to do so, it is used only for the transmission of information necessary for high-speed processing, such as the circuit breaker 31,
Other normal information is transmitted / received by periodically controlling the first internal transmission path 44 using a microcomputer, and is transmitted at a low speed, for example, at a transmission time of 10 ms to several tens of ms, and the units 41a to 41c, It is a method of giving or receiving necessary information between 42a to 42c.

Therefore, when the above information transmission modes are summarized, information is transmitted from the host system 50 to the field control panel 40 and the switchgear main circuit 30, or information is transmitted from the field control panel 40 side to the host system 50. When transmitting, the information is classified according to the processing time (response time) for the importance of each information. For example, it is necessary to urgently drive the circuit breaker 31 in the event of an accident, so-called high-speed response information such as protection relay information requesting so-called high-speed response and operation information of the circuit breaker 31, and control information and maintenance / maintenance
When classified into normal information such as inspection information and transmitted from the host system 50 to the field control panel 40, for example, in the case of high-speed response information, the second external transmission path 52 composed of an electric cable is used, Moreover, each of the units 41a to 41 is routed via the first internal transmission path 43 which is a parallel data bus.
c and circuit breaker drive unit 42a.

Information on the control / monitoring results of the units 41a and 42b obtained from the drive units 42a to 42c is output to the output display unit 41 via the second external transmission line 52.
c, and is transmitted from the output display unit 41c to the host system 50 via the first external transmission path 51. That is, in the case of normal state monitoring and control of switchgear 32, grounding device 33, and other switchgear, high-speed response is not required, so the information output / display unit 41c sends the information to the second internal transmission line. In this system, the data is received from 44 and transmitted to the host system 50 using the first external transmission path 51.

Therefore, according to the configuration of this embodiment, for urgent and important high-speed response information, it passes through the second external transmission line 52 and the first internal transmission line 43 which is a parallel data bus. Since the data is transmitted to each of the units 41a to 41c and the circuit breaker drive unit 42a, necessary measures can be taken promptly when, for example, the circuit breaker is abnormal, and high performance and high reliability can be secured. Moreover, since the on-site control panel 40 is an electronic unit internally, cost reduction and compactness can be realized. (Second Embodiment) FIG. 4 is a block diagram showing another embodiment of the substation equipment according to the present invention.

In this embodiment, the circuit breaker drive unit 42a shown in FIG. 1 is replaced with a circuit breaker drive unit 42a.
There is a dual configuration consisting of 1, 42a2. In this substation, the high-speed response information including the protection relay information, which is the high-speed response from the host system 50, is sent to both drive units 42a1 via the second external transmission path 52.
While the safety of the circuit breaker 31 is ensured by directly introducing the circuit breaker 42a2 to the circuit 42a2, the first of the electronic units 41a to 41c
In this configuration, necessary information is received via the internal transmission path 43 of In addition, the monitoring unit 41b uses the second internal transmission path 44 to drive each of the drive units 42a1, 42a2, 42.
The operating states of b and 42c are monitored.

Then, the monitoring unit 41b transmits the monitoring information of the operating state of each drive unit 42a1, 42a2, 42b, 42c and the like, together with other monitoring information, to the host system 50 via the first external transmission path 51. . The host system 50 receives the monitoring information from the first external transmission path 51, and thereby the field device and the control unit 4
1a, monitoring unit 41b, information output display unit 41
Understand the state of computerized control system such as c.

Therefore, according to the structure of this embodiment, by duplicating the circuit breaker drive unit, the circuit breaker can be fully protected, the safety can be secured, and the higher reliability can be obtained. You can (Third Embodiment) FIG. 5 is a block diagram showing another embodiment of the substation equipment according to the present invention.

This embodiment is an improvement of the electronic unit in the field control panel 40. Specifically, other than the circuit breaker unit 90 and the switch unit 91 corresponding to the circuit breaker and other switching devices. The output display unit 93 outputs the information from the input processing unit 92 which takes in the operating state of each switchgear including the units 90 and 91 and the circuit breaker and performs appropriate processing, and transmits the information to the host system 50. It is provided.

The circuit breaker unit 90 not only performs an operation control function for the circuit breaker 31, but also has a function of accommodating a transmission line corresponding to the first internal transmission line 43 and receiving high-speed response information at high speed.

The switch unit 91 is a switch unit other than the circuit breaker, and has the function of controlling the operation of the disconnector 32, the grounding device 33, and the state monitoring function including the transducers 34b and 34c and the drive unit 42d.

The input processing unit 92 is an interface for inputting and processing information that does not require high speed,
For example, in the case of monitoring control of the circuit breaker hydraulic system, monitoring of gas pressure, etc., a response time of several seconds to several tens of seconds is sufficient at most, so if the unit is configured as a unit different from the units 90 and 91, Space efficiency is good, and circuit configuration within the unit is often easy.

With such a configuration, of the high-speed response information regarding the operation of the circuit breaker 31, the protection relay information is urgent, and therefore the circuit breaker drive unit 42a and the first circuit breaker drive unit 42a are connected via the second external transmission path 52. Is directly introduced into the circuit breaker unit 90 by a transmission line corresponding to the internal transmission line of
The circuit breaker 31 is driven and necessary control is performed.

On the other hand, the position information of the circuit breaker 31 is input to the circuit breaker unit 90 from the position sensor 63 (see FIG. 2) in the transducer 34a via the circuit breaker unit 42a with almost no delay time. Has been done. As a result, in the circuit breaker unit 90, the circuit breaker 3 is always
1, the state of the transducer 34a, the circuit breaker drive unit 42a, etc. is monitored. Since the information of this monitoring result does not require relatively high speed, it is introduced to the output display unit 93 via the internal transmission line 44, and It is transmitted to the host system 50 through the first external transmission line 51.

Therefore, according to the configuration of this embodiment, by incorporating the high-speed transmission function of, for example, protection relay information, which is most important for the control of the circuit breaker 31, in the circuit breaker unit 90, the circuit breaker 31 can be operated at a higher speed. The operation can be realized, and the urgency and reliability can be further improved.

Of the switchgear, the circuit breaker 31 is of the utmost importance, and it is necessary to achieve the highest reliability with respect to the operation relating to its protection. If a circuit breaker unit 90 is duplicated, higher reliability can be secured. (Other Embodiments) In the construction of the embodiment shown in FIGS. 1, 2 and 4, an internal transmission line 43 for high speed transmission and an internal transmission line 44 for low speed transmission are used in the field control panel 40. However, it is also possible to overcome the time difference of information transmission by using one of these transmission lines and controlling the one transmission line by software of the microcomputer in the output display unit 41c or 93, for example. .

That is, the information to be transmitted is classified into high-speed information and low-speed information, and transmission control is preferentially performed for the former high-speed information, or the information refresh time is set to the shortest, and the latter low-speed information is high-speed information. It may be a method of transmitting by utilizing the interval between the processes. In this case, the microcomputer that controls the transmission path needs to operate with a high-speed clock.

In the case of high-speed response information, the parallel bus is used. Since it is transmitted to the computerized unit and the drive unit for important equipment via a high-speed internal transmission line such as, it is possible to take appropriate measures with high speed and high reliability against the failure of substation equipment, and to secure the safety of substation equipment. You can secure the sex.
