【発明の詳細な説明】 この発明は分路リアクトルに関するものである。[Detailed description of the invention] This invention relates to a shunt reactor.
現在の電力系統を第1図に示している。すなわち、Aは

。The current power system is shown in Figure 1. In other words, A is 220-500 and ■ ultra-super high voltage system, ■ is 220-500
0KV/66~154KV primary substation, 2 is 66~1

/100-400V pole transformer, 7 is an electric light consumer.
このような電力系統において、従来第2図のように並列
コンデンサ8以外に、需要家5,7に設置された電力用
コンデンサ9が多く、しかも深夜になって負荷が少なく
なった場合でも電力用コンデンサ9が切離されるケース
が少ないため、進相骨の突き上げが多くなるという問題
がある。そこでこれを補償するため1次変電所1に分路
リアクトル10を設置して超々高圧系統Aへ流入する無
効電力が少なくなるようにしている。In such power systems, conventionally, as shown in Fig. 2, in addition to the parallel capacitor 8, there are many power capacitors 9 installed at consumers 5 and 7, and even when the load decreases late at night, the power capacitors 9 Since there are few cases in which the capacitor 9 is disconnected, there is a problem in that the phase-accelerating bone is often pushed up. Therefore, in order to compensate for this, a shunt reactor 10 is installed in the primary substation 1 to reduce the amount of reactive power flowing into the ultra-super high voltage system A.
ところで、このような分路リアクトル10は、1次変電
所1側に設置するよりも第2図の破線および第3図のよ
うに配電用変電所3側に分路リアクトル11.12を設
置する方が送2電線2に流れる無効電力が少ないため、
送電損失の軽減上有利である。しかし、配電用変電所3
に設置する場合、分路リアクトル11.12の容量が5
〜20MVAと比較的小容量となり、1次変電所lで使
用されている20〜120MVAの大容量のものに比較
して容量当りの費用が高価になる。また配電用変電所3
内にスペースや開閉装置用の用地が新たに必要となる。By the way, rather than installing such a shunt reactor 10 on the primary substation 1 side, the shunt reactor 11.12 is installed on the distribution substation 3 side as shown by the broken line in FIG. 2 and in FIG. 3. Since less reactive power flows to the transmission line 2,
This is advantageous in reducing power transmission losses. However, distribution substation 3
If the capacity of shunt reactor 11.12 is 5.
It has a relatively small capacity of ~20 MVA, and the cost per capacity is higher than the large capacity of 20 to 120 MVA used in the primary substation I. Also, distribution substation 3
Additional space and land for the switchgear will be required within the building.
とくに分路リアクトルを置く必要があるのはケーブル系
の多い人口密度の高い都心部分であるため、なおさら変
電所用地の確保が困難な場所である。したがって配電用
変電所3への設置が困難であり、現在の電力系統では配
電用変電所3に分路リアクトル11.’12が設置され
ることはほとんどない。In particular, it is necessary to install shunt reactors in densely populated urban areas with many cable systems, making it even more difficult to secure land for substations. Therefore, it is difficult to install the shunt reactor 11 in the distribution substation 3 in the current power system. '12 is rarely installed.
したがって、この発明の目的は、送電損失の軽減を図り
、設置スペースを増大しないで配電用変電所側に容易に
設置することができる分路リアクトルを提供することで
ある。Therefore, an object of the present invention is to provide a shunt reactor that reduces power transmission loss and can be easily installed at a power distribution substation without increasing installation space.

遅相分を電力用コンデンサ9の進相分に対応させること
により無効電力を低減し、また変圧作用により配電用変
電所3における変圧器に代用するごとができることとな
る。An embodiment of this invention is shown in FIGS. 4 to 6. That is, in this three-phase shunt reactor, main windings 16a to 16c are provided on the core leg 15 having the gearing 14 of the core 13, and secondary windings 17a to 17c for power distribution voltage are further added, and the turns ratio is 66. -154, the voltage is stepped down to /3.3-22KV. FIG. 5 shows an equivalent circuit of this shunt reactor TrR, which reduces reactive power by making the lagging phase component of the shunt reactor TrR correspond to the leading phase component of the power capacitor 9, and also transforms the distribution substation through the transformer action. This means that it can be used in place of the transformer at point 3.
このように、変圧作用を兼ねた分路リアクトルTrRを

が可能になる。したがって系統全体での合理的な無効電
力のバランスがとれ、送電線での送電損失の軽減を図る
ことができる。In this way, by installing the shunt reactor TrR that also functions as a transformer in place of the conventional transformer as shown in Figure 6, the disconnector P and the Because the distribution equipment for the shunt reactor, including circuit elements such as the disconnector Q, is omitted, the equipment is simplified, and there is no need to add new land or buildings for the distribution substation 3, making it possible to replace the existing distribution equipment. It becomes possible to supply delayed phase reactive power at the distribution substation 3 using almost the same site and equipment cost as a transformer. Therefore, it is possible to achieve a reasonable balance of reactive power in the entire system, and to reduce power transmission losses on power transmission lines.

This has the effect of simplifying local equipment and further reducing power transmission losses.
