66kV Wangjiagou Power Substation

66kV Minshou Power Substation

　　In the substation engineering aspect,there are more successful designings.In the one hand of the 220kV substation,we have fulfilled many design projects of reconstructing ,expanding,moving substations such as Dalian substation,Zhuanghe substation,Shongshu substation,and so on.The complicacy of these projects exceed constructing a entire 220kV substation.In the fulfillment,we have obtained the ability of designing 220kV power substations.In the other hand of the 66kV substation,early in the 80's, we successfully finished the designing of the downtown small-size indoor power substation by using imported equipment, and was granted Science & Technology Progressive Awards in the province, city and Northeast Electric Power Group. In 1998,for the first time,we adopted domestic equipments totally,finished the new mode designing of the small-size indoor power substation,and broke normal designing methods of the small-size indoor power substation used in the last years.66kV indoor power substation went into a new stage on the small-size and adopting domestic equipments. It was granted Science & Technology Progressive Awards in the state,ministry.In the 90's,We had finished the other two new mode designing of the 66kV substation.one mode is an integral whole of civil construction and substation,the other mode is unmanned on duty substation.We had successfully resolved fireproofing,airiness,noise of substation,and so on.We learned foreign advanced principle on unmanned on duty substation,simplified connection and avoided repeated links，non-oil switch equipment, and adopted micro-processing protection, control equipmentand some other automatic facilities.We had realized unmanned on duty power substation.In 1994, we finished the design project of 66kv Victory Square underground power substation,whivh was the largest capacity and scale 66kV underground power substation in the area of Northeast at that time.

　　In the transmission engineering aspect,we have fulfilled more than 1000 design projects of 66kV and 220kV power transmission lines since establishment in 1956. In the early 70's, we successfully finished the designing of 66kV Shicheng Line with a big span 1120 meters(spaning the sea)transmission line reconstruction. In the early 80's, we designed by oneself 66kV transmission tower with double loop and double split lines to meet the need of city electric power network construction,and so as to adapt to network development and improvement. From 80's to now, we have finished over 20 design projects of 66kV cable, and had successful designing experience on the cable subsection and T-connection.

　　We have professional survey personnel engaging in control survey, project survey and topography survey. We have advanced survey instruments such as total station，precision water level, etc, and necessary the project survey software. Our survey personnel is more professional and experienced than the same kind of design institute

Our specialised survey staff

　　In the respect of communication designs,we started to undertake communication design work for electricity power system and power substation since 1997. We have accomplished over 30 projects of optical communication. There are 6 projects of OPGW reuniting the ground line optical cable communication and 5 projects of ADSS optical cable communication among them.Particular on the combination of OPGW reuniting the ground line optical cable and transmission line ,ADSS optical cable and old transmission line reconstruction,we have accumulated much design experience.

　　In the overseas engineering aspect,we started to march abroad in 1997, were engaged in bid for the projects of power transformation and transmission in Bangladesh.At the same year,we were also engaged in the second stage engineering design of 69kV power transformation and transmission projects in Antigua. In 2001, we had a bid for projects of 132kV and 66kV power substation in Nepal.In the fulfillment in the last years, we have gained experience,promoted our personnel ability.

　　　　　　　　　　　Resource arrangement
◆Human resources
　　We have total 58 employees, 10 with senior title for technical personnel, 21 with Intermediate title for technical personnel, 14 engineer assistants, one first-class certificated architect, one first-class certificated building structure engineer, four second-class certificated architects, two second-class certificated building structure engineers, and two certificated evaluators.
　　The institute contains seven professional sections,such as system, power substation, power transmission, construction, communication, technical economy and survey. The most important thing, we think, is the cultivation of qualified personnel, so that we made many restrictions and training programs for it.
