本発明は、工場、ビル等のような建造物内の使用電力量、地絡、漏洩電流等の監視対象情報を上記建造物外または建造物内で一括または集中して監視できる集中監視システムに関するものである。   The present invention relates to a centralized monitoring system that can monitor monitoring target information such as power consumption, ground fault, leakage current, etc. in a building such as a factory or a building collectively or centrally outside or inside the building. Is.

工場、ビル等のような比較的大規模の建造物には受配電変圧器を収容した電気室が設けられており、ここから建造物内に設けられら分電盤または配電盤を介して各設備または各階へ、動力、電灯等の各負荷に電力供給を行っている。電力使用者は監視対象情報として、例えば、各負荷の使用電力量を監視する必要があるために、各負荷に対応して設けられた電力量計を、特許文献１に示されるように、一箇所に集中する場合が多い。この場合、一括または集中された監視対象情報は、例えば、電気室で監視されることになる。   A relatively large-scale building such as a factory or a building is provided with an electrical room that houses a receiving and distributing transformer, and each facility is installed in the building from here through a distribution board or distribution board. Or power is supplied to each load such as motive power and electric light to each floor. Since the power user needs to monitor the amount of power used for each load as the monitoring target information, for example, as shown in Patent Document 1, a power meter provided corresponding to each load is used. Often concentrates on the location. In this case, collective or concentrated monitoring target information is monitored in an electrical room, for example.

また、上記のように一括または集中された監視対象情報を、上記建造物内ではなく建造物外で一括または集中して監視する必要がある場合がある。例えば、特許文献２に示される監視システムでは、監視対象情報を収集した下位系監視装置（変電所監視装置）からデータ伝送路を介して上位系監視装置で監視対象情報が監視されるようになっている。   In addition, there is a case where it is necessary to collectively or centrally monitor the monitoring target information as described above outside the building rather than inside the building. For example, in the monitoring system disclosed in Patent Document 2, the monitoring target information is monitored by the higher level monitoring apparatus via the data transmission path from the lower level monitoring apparatus (substation monitoring apparatus) that collects the monitoring target information. ing.

一方、電力会社の配電系統には、種々の目的のために、電力会社が管轄する中央制御装置から柱上変圧器、地上設置型変圧器装置等の配電機器までの間及び各配電機器間を同軸ケーブル、光ケーブル等からなる伝送用ケーブルがネットワーク状に敷設されている。   On the other hand, for various purposes, the power distribution system of the electric power company has a space between the central control device, which is under the jurisdiction of the electric power company, and power distribution devices such as pole transformers and ground-mounted transformer devices. Transmission cables such as coaxial cables and optical cables are laid in a network.

図４は従来の集中監視システムを示すブロック図である。従来では、電力会社が管轄するデータ伝送路を利用して上記建造物の監視対象情報を、建造物外に位置する電力会社が管轄する上位系監視装置（中央制御装置）で一括または集中して監視できるようにし、また、使用電力量としている。図示するように、建造物１の電気室２には下位系監視装置３００が設けられており、この下位系監視装置３００と電力会社が管轄する上位系監視装置（中央制御装置）４とはデータ伝送路５を介して接続されている。   FIG. 4 is a block diagram showing a conventional centralized monitoring system. Conventionally, the monitoring target information of the above-mentioned building is centrally or concentrated on the higher-level monitoring device (central control device) that is controlled by the power company located outside the building using the data transmission path that is controlled by the power company. It is possible to monitor the power consumption. As shown in the figure, a lower system monitoring device 300 is provided in the electrical room 2 of the building 1, and the lower system monitoring device 300 and the upper system monitoring device (central control device) 4 under the jurisdiction of the electric power company are data. They are connected via a transmission line 5.

データ伝送路５は、電力会社が管轄するデータ伝送路５Ａ及び電力使用者側が管轄するデータ伝送路５Ｂからなり、データ伝送路５Ａは上位系監視装置４から柱上変圧器、地上設置型変圧器装置等の配電機器１３まで、データ伝送路５Ｂはこの配電機器１３から建造物１までとする。なお、データ伝送路５は同軸ケーブルとしている。   The data transmission path 5 includes a data transmission path 5A managed by the power company and a data transmission path 5B managed by the power user side. The data transmission path 5A is connected to the pole-mounted transformer, the ground-mounted transformer from the host system monitoring device 4. The data transmission path 5B extends from the power distribution device 13 to the building 1 up to the power distribution device 13 such as a device. The data transmission path 5 is a coaxial cable.

建造物１が比較的大規模の場合、電気室２が設けられており、電気室２に収容されている受配電変圧器６には、建造物１内に配線された電力線７が接続されている。電力線７は、例えば、３つの配電盤または分電盤８ａ，８ｂ，８ｃにそれぞれ接続されるように分岐され、分岐した分岐線７ａ，７ｂ，７ｃに配電盤または分電盤８ａ，８ｂ，８ｃを介して負荷９ａ，９ｂ，９ｃがそれぞれ接続されている。   When the building 1 is relatively large, an electrical room 2 is provided, and a power line 7 wired in the building 1 is connected to the power receiving and distribution transformer 6 accommodated in the electrical room 2. Yes. The power line 7 is branched so as to be connected to, for example, three distribution boards or distribution boards 8a, 8b, and 8c, and the branched branch lines 7a, 7b, and 7c are connected to the distribution boards or distribution boards 8a, 8b, and 8c. The loads 9a, 9b, 9c are connected to each other.

電気室２には、負荷９ａ，９ｂ，９ｃに対応して設けられた電力量計１０ａ，１０ｂ，１０ｃが収容されている。各電力量計１０ａ，１０ｂ，１０ｃには、監視対象情報（使用電力量）の元情報として、変圧器６の二次側電圧がそれぞれ入力されている。また、例えば、配電盤または分電盤８ａ，８ｂ，８ｃ内にそれぞれ設けられた監視対象情報（使用電力量）の元情報を得るセンサーとして、変流器１１ａ，１１ｂ，１１ｃにより検出される負荷電流がそれぞれのケーブル１２ａ，１２ｂ，１２ｃを介して入力されている。   In the electric chamber 2, watt hour meters 10a, 10b, 10c provided corresponding to the loads 9a, 9b, 9c are accommodated. Each power meter 10a, 10b, 10c is input with the secondary voltage of the transformer 6 as the original information of the monitoring target information (power consumption). Further, for example, load currents detected by the current transformers 11a, 11b, and 11c as sensors for obtaining original information of monitoring target information (power consumption) provided in the switchboards or distribution boards 8a, 8b, and 8c, respectively. Are input via the cables 12a, 12b, and 12c.

下位系監視装置３００は下位系データ収集部３００ａと下位系データ処理部３００ｂと下位系通信部３００ｃとを備え、上位系監視装置４からの一定周期のポーリング信号を受信すると、下位系データ収集部３００ａでは各電力量計１０ａ，１０ｂ，１０ｃ，１０ｄにより得られた監視対象情報（使用電力量）を収集し、下位系データ処理部３ｂでは収集された監視対象情報（使用電力量）を伝送信号に変換し、下位系通信部３００ｃでは変換された伝送信号をデータ伝送路５に送出する。なお、下位系通信部３００ｃにはデータ伝送路５Ｂと接続するための図示しない伝送インターフェースが組み込まれている。   The lower system monitoring device 300 includes a lower system data collection unit 300a, a lower system data processing unit 300b, and a lower system communication unit 300c. When the lower system data collection unit 300c receives a polling signal with a certain period from the upper system monitoring device 4, the lower system data collection unit In 300a, the monitoring target information (power consumption) obtained by each watt-hour meter 10a, 10b, 10c, 10d is collected, and in the lower system data processing unit 3b, the collected monitoring target information (power consumption) is transmitted as a transmission signal. The lower communication unit 300 c sends the converted transmission signal to the data transmission path 5. The lower-level communication unit 300c incorporates a transmission interface (not shown) for connecting to the data transmission path 5B.

上位系監視装置４は、上位系通信部４ａと上位系データ処理部４ｂと表示部４ｃとを備え、上位系通信部４ａでは下位系監視装置３から送信された伝送信号を受信し、上位系データ処理部４ｂでは受信した伝送信号を監視対象情報に変換し、表示部４ｃでは変換された監視対象情報をモニタ等に表示する。なお、上位系監視装置４は、監視対象情報の解析も行う。なお、上位系通信部４ａにはデータ伝送路５Ａと接続するための伝送インターフェースが組み込まれている。   The host system monitoring device 4 includes a host system communication unit 4a, a host system data processing unit 4b, and a display unit 4c. The host system communication unit 4a receives a transmission signal transmitted from the lower system monitoring device 3, and receives the host system. The data processing unit 4b converts the received transmission signal into monitoring target information, and the display unit 4c displays the converted monitoring target information on a monitor or the like. The host system monitoring device 4 also analyzes monitoring target information. The upper system communication unit 4a incorporates a transmission interface for connecting to the data transmission path 5A.

この例では、各負荷９ａ，９ｂ，９ｃを接続している分岐線７ａ，７ｂ，７ｃの電圧値と電力線７の電圧値とを同じとしているので、変圧器２の二次側に配線された電力線７の接続箇所から各電力量計１０ａ，１０ｂ，１０ｃまで、電圧検出線７１が引き出され、その電圧検出線７１の電圧がそれぞれ入力されている。したがって、変流器１１ａ，１１ｂ，１１ｃにより検出される電流のみがケーブル１２ａ，１２ｂ，１２ｃを介してそれぞれ入力されている。
特開２００３−２２２６４５号公報（図７） 特開平１０−２５７６７３号公報（図１） In this example, the voltage values of the branch lines 7a, 7b, 7c connecting the loads 9a, 9b, 9c and the voltage value of the power line 7 are the same, so that they are wired to the secondary side of the transformer 2 The voltage detection line 71 is drawn out from the connection place of the power line 7 to each watt hour meter 10a, 10b, 10c, and the voltage of the voltage detection line 71 is inputted. Accordingly, only currents detected by the current transformers 11a, 11b, and 11c are input via the cables 12a, 12b, and 12c, respectively.
