The procurement plan for the 35kV booster station reconstruction project of Sichuan Fenghuang Hydropower Co., Ltd. power generation company Longfeng Hydropower Station has been approved. Upon the entrustment of the purchaser, it is proposed that the 35kV booster station of the Sichuan Power Company Limited power generation company Longfeng Hydropower Station be reconstructed. Competitive negotiation is used for procurement, and suppliers are welcome to participate in the competitive negotiation of the project (hereinafter referred to as “respondentâ€). The relevant issues are now described as follows:
I. Project Name: Reconstruction of the 35kV booster station of Sichuan Longfeng Hydropower Station, Sichuan Star Power Co., Ltd.
II. Project address: Longfeng Hydropower Station, Longfeng Ancient Town, Chuanshan District, Suining City
III. Construction Scale and Capacity:
(I) Status of booster station
The substation is located in Longping Village, Chuanshan District. The current booster station is:
1) Main transformer capacity: 1# main transformer 1×5MVA 38.5/10.5/3.15kV has been built, and 2# main transformer 1×4MVA 38.5/3.15kV.
2) 35kV part: Single busbar connection type, 35kV outgoing line 3 times, 35kV dragon line, 35kV dragon line, 35kV dragon antenna. The 35kV power distribution device adopts the general medium-sized layout of the outdoor soft bus.
3) 10kV part: Single busbar connection type, 10kV outgoing line 4 times, 10kV LongLao line, 10kV Long Front line, 10kV LongPass line, factory power system, and 10kV single busbar connection form. The 10kV power distribution device adopts a fixed switchgear type.
4), 3.15kV part: using a single bus sectional wiring type, 3.15kVI section access 1#, 2#, 3# generator, 3.15kVII section access 4#, 5# generator.
(B), the existence of hidden dangers and the necessity of transformation
The booster station of Longfeng Hydropower Station was built in the 1950s and is mainly responsible for the load on the south of the urban area of ​​the system. The 35kV circuit-breaker at the booster station in the early days of the establishment was a multi-oil circuit breaker. In 2011, the oil-free retrofit was replaced by an SF6 circuit breaker. The 35kV isolation barrier was a GW5-35II(W) type, and it has not been replaced since the establishment of the station. Only regular maintenance and repairs are conducted every year. Due to the long service life of this switch, there are often signs of mechanical sticking and poor contact.
To solve the above problems, the 35kV booster isolation barrier at Longfeng Hydropower Station should be replaced as soon as possible to ensure the safe operation of the system equipment.
Fourth, plan implementation time, duration: 45 days (Gregorian calendar).
V. Source of funds: self-raised funds

VII. Acquisition of procurement documents
Incremental Encoder is commonly used, and Absolute Encoder is used if there are strict requirements on position and zero position. Servo system should be analyzed in detail, depending on the application situation. Commonly used incremental encoder for speed measurement, which can be used for infinite accumulation measurement; Absolute encoder is used for position measurement, and the position is unique (single or multiple turns). Finally, it depends on the application situation and the purpose and requirements to be realized.
