Description

本発明は、停電検出システムおよび停電範囲判定方法に関し、特に、無人の設備（通信局舎など）において停電の原因が配電線側（電力会社側）にあるのか設備側にあるのかを判定するのに好適な停電検出システムおよびこの停電検出システムを用いた停電範囲判定方法に関する。   The present invention relates to a power failure detection system and a power failure range determination method, and in particular, determines whether the cause of a power failure is on the distribution line side (electric power company side) or on the facility side in an unmanned facility (such as a communication station building). And a power failure range determination method using the power failure detection system.

従来、山上などに建てられた無人の通信局舎において停電が発生すると、たとえば図６に示すように、通信局舎内の分岐ブレーカ４ａの負荷側に設置してある無停電電源装置５（停電時以外は交流電圧を直流電圧に変換して通信機器などに供給し、停電時には蓄電池６からの直流電圧を通信機器などに供給する装置）の交流側に設けられた不足電圧継電器（不図示）によって停電を検出して、検出した停電情報を監視装置７によってネットワークを介して遠方の監視センターに伝送している。   Conventionally, when a power failure occurs in an unmanned communication station built on a mountain or the like, for example, as shown in FIG. 6, the uninterruptible power supply 5 (power failure) installed on the load side of the branch breaker 4a in the communication station. An undervoltage relay (not shown) provided on the AC side of a device that converts AC voltage to DC voltage and supplies it to communication devices, etc., and supplies DC voltage from the storage battery 6 to communication devices during a power failure. Is detected, and the detected power failure information is transmitted to the remote monitoring center via the network by the monitoring device 7.

監視センターの担当者は、停電時の天候などから配電線停電によるものか否かを経験的に推測し、しばらく様子を見て、停電が長時間続くような場合には、電力会社へ配電線停電が継続していないか問合せをして確認をしている。   The person in charge at the monitoring center infers empirically whether or not it is due to a power line power outage from the weather at the time of the power outage, etc. An inquiry is made to see if the power outage continues.

しかし、電力会社では末端の高圧配電線や低圧配電線まで監視できているわけではないため、停電を認識できない場合がある。このような場合には、通信局舎へ保守員を派遣し、一般的には主ブレーカ３の電源側（１次側）にテスターを接続して、主ブレーカ３の電源側に商用電圧があれば配電線側は正常であって停電の原因は設備側（通信局舎側）と判断することにより、停電の原因が配電線側にあるのか設備側にあるのかを判断している。   However, power companies may not be able to monitor the high-voltage distribution lines and low-voltage distribution lines at the end, and may not be able to recognize power outages. In such a case, a maintenance staff is dispatched to the communication station building, and generally a tester is connected to the power source side (primary side) of the main breaker 3 so that a commercial voltage is present on the power source side of the main breaker 3. For example, the distribution line side is normal and the cause of the power outage is determined to be the equipment side (communication station side), thereby determining whether the power outage is on the distribution line side or the equipment side.

なお、本出願人は、下記の特許文献１において、停電原因が分電盤より屋内側なのか屋外側なのかをユーザが目視により直接的に認識可能とするために、第１の巻き取り装置が、主ブレーカの負荷側から電源の供給を受け、屋内が停電した旨の記載がなされた第１の表示プレートを非表示位置に保持し、第２の巻き取り装置が、主ブレーカの電源側から電源の供給を受け、屋外が停電した旨の記載がなされた第２の表示プレートを非表示位置に保持して、停電原因が屋内側にあるときは、第１の表示プレートの保持状態を解除して第１の表示プレートを表示位置に移動させることにより、ユーザがその記載内容から屋内側に停電原因があると認識でき、停電原因が分電盤より屋外側にあるときは、第１および第２の表示プレートの保持状態を解除して第１および第２の表示プレートを表示位置に移動させることにより、ユーザが第２の表示プレートの記載内容から屋外側に停電原因があると認識できるようにした停電表示装置を提案している。   In addition, in order to make it possible for the user to directly recognize visually whether the cause of the power failure is on the indoor side or the outdoor side from the distribution board, However, the power supply is supplied from the load side of the main breaker, the first display plate on which the indoor power failure has been described is held in the non-display position, and the second winding device is connected to the power source side of the main breaker. When the second display plate that has received the power supply from the outside and has been informed that the power failure has occurred outside is held in the non-display position and the cause of the power failure is on the indoor side, the holding state of the first display plate By canceling and moving the first display plate to the display position, the user can recognize that there is a cause of power failure on the indoor side from the description, and when the cause of power failure is on the outdoor side from the distribution board, And the holding state of the second display plate The power failure display device has been proposed in which the first and second display plates are moved to the display position so that the user can recognize that there is a power failure cause on the outdoor side from the description on the second display plate. ing.

また、本出願人は、下記の特許文献２において、需要家による停電時の代替電源の確保を容易にするとともに電力会社から確実に代替電源を需要家に提供することを可能にするために、予め充電された直流電力を交流電力に変換して代替電力として出力可能な代替電源装置と、宅外に設けられ、系統電力の停電を検知すると、代替電力の出力を代替電源装置に指示するとともに、代替電源装置からの代替電力を出力する屋外装置と、宅内に設けられ、系統電力を所定機器に出力し、屋外装置が停電を検知すると、屋外装置が出力する代替電力を所定機器に供給する屋内装置とを備えた系統電力代替電源装置を提案している。   In addition, in the following Patent Document 2, the present applicant makes it easy to secure an alternative power source at the time of a power outage by a consumer and to reliably provide the alternative power source from the power company to the customer. An alternative power supply device that can convert precharged DC power to AC power and output it as alternative power, and is provided outside the home. When a power failure of the system power is detected, the alternative power supply device is instructed to output the alternative power An outdoor device that outputs alternative power from the alternative power supply device, and a home power supply that outputs system power to a predetermined device. When the outdoor device detects a power failure, the alternative power output from the outdoor device is supplied to the predetermined device. The system power alternative power supply device provided with the indoor device is proposed.

しかしながら、上述した無停電電源装置５の不足電圧継電器によって検出した停電情報を監視装置７によってネットワークを介して監視センターに伝送する方法では、停電が長時間続いた場合には、保守員を通信局舎（現地）に派遣して主ブレーカ３の電源側の電圧を測定しないと停電の原因が判断できないという問題のほか、保守員を通信局舎に派遣しても、配電線側に停電の原因がある場合には、保守員は何も対処することができないため、不要な動員になるという問題があった。   However, in the method of transmitting the power failure information detected by the undervoltage relay of the uninterruptible power supply 5 described above to the monitoring center via the network by the monitoring device 7, if the power failure continues for a long time, the maintenance staff is sent to the communication station. In addition to the problem that the cause of the power outage cannot be determined unless the voltage on the power supply side of the main breaker 3 is measured by dispatching to the building (site), the cause of the power outage on the distribution line side even if the maintenance staff is dispatched to the communication station building When there is, there is a problem that maintenance personnel can not deal with anything and become unnecessary mobilization.

また、上記特許文献１で提案した停電表示装置のように主ブレーカ３の電源側（１次側）および負荷側（２次側）の電圧を測定することにより停電の原因が配電線側にあるのか設備側にあるのかを判定することも考えられるが、通信局舎のように山上などの雷の影響が大きい設備では、雷サージを逃がすための耐雷トランス（耐雷Ｔｒ）２が、通信局舎外に設置された電力量計１と通信局舎内に設置された主ブレーカ３との間に設置されている。一般的に耐雷トランス２は設備側の責任とされているため、停電の原因が配電線側にあるのか設備側にあるのかを正確に判定するためには停電の原因が少なくとも耐雷トランス２の前後のいずれであるかを判断した方がよいという問題があった。   Moreover, the cause of the power failure is on the distribution line side by measuring the voltage on the power source side (primary side) and the load side (secondary side) of the main breaker 3 as in the power failure display device proposed in Patent Document 1 above. It is conceivable to determine whether it is on the facility side or not, but in facilities such as a communication station where there is a large lightning effect such as on the mountain, a lightning-resistant transformer (lightning-resistant Tr) 2 for escaping the lightning surge is used in the communication station. It is installed between the watt-hour meter 1 installed outside and the main breaker 3 installed in the communication station building. Generally, the lightning transformer 2 is assumed to be the responsibility of the equipment side, so in order to accurately determine whether the cause of the power failure is on the distribution line side or on the equipment side, the cause of the power failure is at least before or after the lightning transformer 2 There was a problem that it was better to judge which one of these.

本発明の目的は、無人の設備に保守員を派遣することなく停電の原因を判定することができる停電検出システムおよびこの停電検出システムを用いて停電範囲を総合的に判定することができる停電範囲判定方法を提供することにある。   An object of the present invention is to provide a power failure detection system capable of determining the cause of a power failure without dispatching maintenance personnel to an unmanned facility, and a power failure range capable of comprehensively determining a power failure range using the power failure detection system. It is to provide a determination method.

受光装置１２は、通信局舎内に設置されており、光ケーブル１３を介して発光装置１２からの受光した光レベルが所定の閾値以上であるとハイレベルの出力信号を停電判定装置１４に出力する。
なお、発光装置１１と受光装置１２との間を接続する伝送媒体として絶縁体である光ケーブル１３を用いているため、雷が発生しても光ケーブル１３が通信局舎内への雷サージの侵入経路になることを防止することができる。 The light receiving device 12 is installed in a communication station, and outputs a high-level output signal to the power failure determination device 14 when the light level received from the light emitting device 12 via the optical cable 13 is equal to or higher than a predetermined threshold. .
In addition, since the optical cable 13 which is an insulator is used as a transmission medium for connecting between the light emitting device 11 and the light receiving device 12, even if lightning occurs, the optical cable 13 enters the lightning surge intrusion into the communication station. Can be prevented.

停電判定装置１４は、以下に示すようにして停電の原因が配電線側にあるか設備側にあるかを判定して（図２参照）、判定結果を示す判定結果データを監視装置７に出力する。
（１）受光装置１２の出力信号がハイレベル（発光装置１１が発光）であり、かつ、無停電電源装置５の不足電圧継電器の出力信号がロウレベル（停電不検出）であると、「正常（停電なし）」と判定する。
（２）受光装置１２の出力信号がハイレベル（発光装置１１が発光）であり、かつ、無停電電源装置５の不足電圧継電器の出力信号がハイレベル（停電検出）であると、「停電の原因は設備側にある」と判定する。
（３）受光装置１２の出力信号がロウレベル（発光装置１１が不発光）であり、かつ、無停電電源装置５の不足電圧継電器の出力信号がロウレベル（停電不検出）であると、「判定異常」と判定する。

(2) If the output signal of the light receiving device 12 is at a high level (the light emitting device 11 emits light) and the output signal of the undervoltage relay of the uninterruptible power supply 5 is at a high level (power failure detection), The cause is on the equipment side.
(3) If the output signal of the light receiving device 12 is low level (the light emitting device 11 does not emit light) and the output signal of the undervoltage relay of the uninterruptible power supply 5 is low level (no power failure detected), “determination error” Is determined.

監視装置７は、停電判定装置１４から入力される判定結果データを監視センターにネットワークを介して伝送する。   The monitoring device 7 transmits the determination result data input from the power failure determination device 14 to the monitoring center via the network.

以上のように構成された停電検出システムを用いることにより、停電が発生しても、保守員を通信局舎に派遣することなく、かつ、停電の発生時点で停電の原因が配電線側か設備側かを監視センターで把握することができる。   By using the power outage detection system configured as described above, even if a power outage occurs, maintenance personnel are not dispatched to the communication station building, and the cause of the power outage is the distribution line side or equipment at the time of the power outage The monitoring center can grasp whether it is on the side.

以上の説明では、無停電電源装置５の交流側に設けられた不足電圧継電器を設備側電圧検出手段として使用したが、図３に示すように通信局舎内に設置された主ブレーカ３の負荷側（２次側）に電圧検出装置２１（商用電圧を検出するとハイレベルの出力信号を出力する装置）を取り付けて、電圧検出装置２１を設備側電圧検出手段として使用してもよい。   In the above description, the undervoltage relay provided on the AC side of the uninterruptible power supply 5 is used as the facility-side voltage detection means, but the load of the main breaker 3 installed in the communication station as shown in FIG. A voltage detection device 21 (a device that outputs a high-level output signal when a commercial voltage is detected) may be attached to the side (secondary side), and the voltage detection device 21 may be used as equipment-side voltage detection means.

この場合には、停電判定装置１４は、受光装置１２の出力信号と電圧検出装置２１の出力信号とに基づいて、以下に示すようにして停電の原因が配電線側にあるか設備側にあるかを判定して（図４参照）、判定結果を示す判定結果データを監視装置７に出力する。
（１）受光装置１２の出力信号がハイレベル（発光装置１１が発光）であり、かつ、電圧検出装置２１の出力信号がハイレベル（電圧検出）であると、「正常（停電なし）」と判定する。

（４）受光装置１２の出力信号がロウレベル（発光装置１１が不発光）であり、かつ、電圧検出装置２１の出力信号がロウレベル（電圧不検出）であると、「停電の原因は配電線側にある」と判定する。 In this case, the power failure determination device 14 is based on the output signal of the light receiving device 12 and the output signal of the voltage detection device 21, and the cause of the power failure is on the distribution line side or on the equipment side as shown below. Is determined (see FIG. 4), and determination result data indicating the determination result is output to the monitoring device 7.

(3) When the output signal of the light receiving device 12 is low level (the light emitting device 11 does not emit light) and the output signal of the voltage detecting device 21 is high level (voltage detection), it is determined as “determination abnormality”.
(4) When the output signal of the light receiving device 12 is low level (the light emitting device 11 does not emit light) and the output signal of the voltage detecting device 21 is low level (voltage is not detected), “the cause of the power failure is the distribution line side It is determined.

また、以上の説明では、電力量計１を財産分界点としたが、電気供給約款で示されている低圧引込線の引込線第１支持点（顧客の建造物または補助支持物）の支持がいしの負荷側接続点を財産分界点としてもよい。
この場合には、図１に示した電力量計１よりも配電線側（耐雷トランス２と反対側）に位置する引込線第１支持点の支持がいしの負荷側接続点に発光装置１１を設置する。 In the above description, the watt-hour meter 1 is the property demarcation point. However, the load of the support insulator for the first support point (customer's building or auxiliary support) of the low-voltage service line shown in the electricity supply agreement. The side connection point may be the property demarcation point.
In this case, the light emitting device 11 is installed at the load-side connection point of the support lead of the lead-in wire first support point located on the distribution line side (opposite side of the lightning resistant transformer 2) from the watt-hour meter 1 shown in FIG. .

次に、本発明の停電範囲判定方法の実施例について図５を参照して説明する。
山上無線中継所は電波の見通しが良いことから山頂付近に設置されるが、このような場所は限られることから、たとえば県防災無線中継所、警察無線中継所、ＮＴＴ中継所、テレビ・ラジオ放送局、携帯電話基地局などが集中して設置されていることが多い。
したがって、判定結果が「停電の原因は配電線側にある」であれば、通信回線を介して配電線の保守をする電力会社の営業所に通知して配電自動化システムと連係させることにより、配電線の早期復旧が期待できる。また、電力会社の無線中継所に本発明の停電検出システムを備えることにより、自営社内通信回線を用いて停電検出システムと配電自動化システムとを接続することは容易である。
また、同じ高圧配電線を使用している設備が停電しているのか、同じ変圧器の負荷側が停電しているのか、低圧引込線単独の停電であるのかを総合的に判定するには、配電線の状況と負荷側の状況を組み合わせることが有効なケースがある。 Next, an embodiment of the power failure range determination method of the present invention will be described with reference to FIG.
The Yamagami Radio Relay Station is installed near the top of the mountain due to good radio wave visibility, but such places are limited. For example, the Prefectural Disaster Prevention Radio Relay Station, Police Radio Relay Station, NTT Relay Station, TV / Radio Broadcasting Stations and mobile phone base stations are often concentrated.
Therefore, if the judgment result is “the cause of the power outage is on the distribution line side”, it is notified to the sales office of the electric power company that maintains the distribution line via the communication line and linked to the distribution automation system. Early recovery of electric wires can be expected. Moreover, by providing the power company wireless relay station with the power failure detection system of the present invention, it is easy to connect the power failure detection system and the power distribution automation system using a self-employed in-house communication line.
In addition, to comprehensively determine whether equipment using the same high-voltage distribution line is out of power, whether the load side of the same transformer is out of power, or a low-voltage service line alone, the distribution line There are cases where it is effective to combine the situation on the load side and the situation on the load side.

そこで、図５に示すように、配電線幹線３１から分岐された配電線支線３２（高圧配電線）に３本の低圧配電線３３ａ〜３３ｃが３個の柱上変圧器４５ａ〜４５ｃを介してそれぞれ分岐された電力系統において、配電線幹線３１に設置された変電所遮断器４１、配電幹線３１の配電支線３２の分岐点の前後に設置された２個の開閉器４２ａ，４２ｂおよび配電線支線４２ｃに設置された開閉器４２ｃと配電自動化システム４４が電力会社のネットワーク４３を介して接続されているとともに、低圧配電線３３ａから分岐された２本の低圧引込線３４Ａ，３４ＢからＡ社およびＢ社無線中継所５１Ａ，５１Ｂが商用電圧をそれぞれ供給されており、低圧配電線３３ｂから分岐された低圧引込線３４ＣからＣ社無線中継所５１Ｃが商用電圧を供給されており、低圧配電線３３ｃから分岐された低圧引込線３４ＤからＤ社無線中継所５１Ｄが商用電圧を供給されている場合には、図１または図３に示した停電検出システムをＡ社、Ｂ社、Ｃ社およびＤ社無線中継所５１Ａ〜５１Ｄに設置して、各停電検出システムの監視装置７から判定結果データを配電自動化システム４４に通信回線（不図示）を介して送信する。   Therefore, as shown in FIG. 5, three low voltage distribution lines 33a to 33c are connected to three distribution line branch lines 32 (high voltage distribution lines) branched from the distribution line trunk line 31 via three pole transformers 45a to 45c. In each branched power system, a substation circuit breaker 41 installed on the distribution line main line 31, two switches 42 a and 42 b installed before and after the branch point of the distribution branch line 32 of the distribution main line 31, and a distribution line branch line The switch 42c installed in 42c and the distribution automation system 44 are connected via the network 43 of the electric power company, and from the two low-voltage service lines 34A and 34B branched from the low-voltage distribution line 33a, the companies A and B The wireless relay stations 51A and 51B are respectively supplied with commercial voltages, and the company C wireless relay station 51C supplies commercial voltages from the low-voltage service line 34C branched from the low-voltage distribution line 33b. When the company D radio relay station 51D is supplied with a commercial voltage from the low-voltage service line 34D branched from the low-voltage distribution line 33c, the power failure detection system shown in FIG. Company, C company and D company wireless relay stations 51A to 51D are installed, and determination result data is transmitted from the monitoring device 7 of each power failure detection system to the distribution automation system 44 via a communication line (not shown).

これにより、たとえば配電線支線３２に設置された開閉器４２ｃから開閉器４２ｃが投入されたことを示す信号（開閉器４２ｃの開閉状態を示す信号。以下、「開閉器状態信号」と称する。）が送信されてくるとともにＡ社、Ｂ社、Ｃ社およびＤ社無線中継所５１Ａ〜５１Ｄに設置した停電検出システムの監視装置７すべてから「停電範囲は配電線側にある」との判定結果データが送信されてくると、配電自動化システム４４では「同じ高圧配電線（配電線支線３２）を使用している設備が停電している」と判定することができる。
また、開閉器４２ｃが投入されたことを示す開閉器状態信号が送信されてきているときにＡ社、Ｂ社、Ｃ社およびＤ社無線中継所５１Ａ〜５１Ｄに設置した停電検出システムの監視装置７の少なくとも１つから「停電範囲は配電線側にある」との判定結果データが送信されてくると、配電自動化システム４４ではＡ社、Ｂ社、Ｃ社およびＤ社無線中継所５１Ａ〜５１Ｄに設置した停電検出システムのいずれの監視装置７から判定結果データが送信されてきたかにより、停電個所が柱上変圧器４５ａ〜４５ｃおよび低圧引込線３４Ａ〜３４Ｄのいずれであるかを判定することができる。
その結果、たとえば開閉器４２ｃが投入されたことを示す開閉器状態信号が送信されてきているときにＡ社およびＢ社無線中継所５１Ａ，５１Ｂに設置した停電検出システムの監視装置７のみから「停電範囲は配電線側にある」との判定結果データが送信されてくると、配電自動化システム４４では「同じ変圧器（柱上変圧器４５ａ）の負荷側が停電している」と判定することができる。
また、たとえば開閉器４２ｃが投入されたことを示す開閉器状態信号が送信されてきているときにＡ社無線中継所５１Ａに設置した停電検出システムの監視装置７のみから「停電範囲は配電線側にある」との判定結果データが送信されてくると、配電自動化システム４４では「低圧引込線（低圧引込線３４Ａ）単独の停電である」と判定することができる。 Thereby, for example, a signal indicating that the switch 42c is inserted from the switch 42c installed in the distribution line branch line 32 (a signal indicating an open / closed state of the switch 42c. Hereinafter, referred to as a “switch state signal”). Is transmitted, and all the monitoring devices 7 of the power failure detection system installed at the wireless relay stations 51A to 51D of Company A, Company B, Company C, and Company D determine that the power failure range is on the distribution line side. Is transmitted, the distribution automation system 44 can determine that “the facility using the same high-voltage distribution line (distribution line branch line 32) has a power failure”.
Moreover, when the switch state signal which shows that the switch 42c was thrown in is transmitted, the monitoring apparatus of the power failure detection system installed in A company, B company, C company, and D company wireless relay station 51A-51D When the determination result data that “the power outage range is on the distribution line side” is transmitted from at least one of 7, the distribution automation system 44 uses the wireless relay stations 51 </ b> A to 51 </ b> D of Company A, Company B, Company C, and Company D. Depending on which of the monitoring device 7 of the power failure detection system installed in the power source has received the determination result data, it can be determined whether the power failure location is the pole transformers 45a to 45c or the low voltage lead-in wires 34A to 34D. .
As a result, for example, when the switch state signal indicating that the switch 42c is turned on is transmitted, only the monitoring device 7 of the power failure detection system installed in the wireless relay stations 51A and 51B of the A company and the B company “ When the determination result data that “the power outage range is on the distribution line side” is transmitted, the distribution automation system 44 determines that “the load side of the same transformer (post transformer 45a) is out of power”. it can.
Further, for example, when the switch state signal indicating that the switch 42c is turned on is transmitted, only the monitoring device 7 of the power failure detection system installed in the wireless relay station 51A of Company A indicates that the power failure range is on the distribution line side. When the determination result data “is present” is transmitted, the distribution automation system 44 can determine that “the low-voltage service line (low-voltage service line 34A) is a single power failure”.
