在崇山峻岭的云南，电力基础设施落后，受天气影响大，导致停电基站分布广、频次高、占比高、历时长。2017年，云南铁塔配套站点共计82626个站点，全年停电次数304万次，月均停电次数25万次，单站月均停电3.31次；全年停电站点58万个，月均停电站点48489个，月均停电站点数占总站点数比例为63.16%；2017年平均单次停电时长为4.35小时；以2017年8月为例，全省共计停电次数为40.8万次，单站月均停电5次；停电站点5.94万个，停电站点占总站点数比例为72.81%。

上述这些带来直接的影响就是发电范围广，次数多，发电成本高。据统计，2017年共发电次数103万次，月均发电次数 8.6万次；发电站点38万个，月均发电站点数量3.19万个；2017年单站月均发电次数1.13次，单次发电平均时长7.72小时，停电站点发电比例平均为34%；2017年蓄电池保障未退服比例平均为38%。以2017年8月为例，停电量占全国的11.5%，发电10.7万站次，发电费3102万元。更直接的影响在于停电频繁，导致铅酸蓄电池容量衰减严重，循环寿命短；导致蓄电池投资居高不下，难以承受。

通过开展梯级电池应用探索发现，梯级电池相比铅酸电池在循环寿命、能量密度、高温性能等方面具备一定优势，各项性能指标优于铅酸电池。特别是退役磷酸铁锂电池循环寿命达到2000次，充分满足频繁停电的维护环境。而且梯次电池环境适应能力（耐高温）强，后续针对采用梯级电池的站点，可采用智能通风系统替代空调，从而降低维护成本投入，也可为后续电费包干奠定基础。

2017年云南是全国梯级电池试点省，通过商务平台共采购梯级电池10605组，涉及2608个站点的更新改造，共计61.7万安时。以西双版纳站点嘎洒公路管理所为例，蓄电池容量计算方法为：电池采购价=采购单价×配置容量×电压，梯级电池比铅酸电池采购费用降低720元，约占铅酸电池采购价的5.8%。以该站停电频次，铅酸电池使用寿命为1年，梯级电池可达3年，铅酸电池年消耗成本达12480元，梯级电池达3920元，只是铅酸电池平均年消耗成本的31.4%，试点取得明显成效。

在维护方面，针对梯级电池使用站点，开展不同参数设置条件进行充放电测试，并结合各梯级电池厂家均充、浮充设置要求，综合考虑，规范不同梯级电池厂家均充、浮充、充电限流、一次下电电压、二次下电电压、电池容量等参数设置要求，在大范围内解决了维护难题。

与此同时，云南铁塔积极与运营商沟通协调，取得运营商支持，鼓励铁塔开展电池更换。针对蓄电池备电时长问题，与云南移动达成共识并签订了备忘录，铁塔新建站址及存量站的基础蓄电池保障备电时长为3小时，针对“超出蓄电池保障备电时长的电池续航支撑服务和发电服务统一按照发电服务结算费用”。

梯级电池作为备电设备，适合云南停电频繁特点，2018年云南将继续扩大梯级电池的使用范围。目前，中国铁塔已下发了梯级电池企业标准，并在运维监控平台开发了梯级电池管理模块，“信号字典表”也单独定义了梯级电池信息，为产品标准化、管理规范化、性能评估数值化进行了努力，但作为长期项目，仍需大家共同努力。

In the mountains of Yunnan, the power infrastructure is backward, affected by weather, resulting in a wide distribution of blackouts base stations, high frequency, high proportion, long duration. In 2017, a total of 82 626 stations were set up in Yunnan Iron Tower, with a total of 3.4 million power outages, 250,000 power outages per month, and 3.31 power outages per month for a single station; 580,000 power outages per month, with an average of 48,489 power outages per month, accounting for 63.16% of the total; and an average of 4.35 power outages per month in 2017. In August 2017, for example, the total number of blackouts in the province was 408,000, with a monthly average of five blackouts per station; 59,400 blackouts occurred at stations, accounting for 72.81% of the total number of blackouts.

The above direct impact is the wide range of power generation, high frequency and high cost of generating electricity. According to statistics, there will be 1.03 million generating times and 86,000 generating times per month in 2017; 380,000 generating stations and 31,900 generating stations per month; 1.13 generating times per month in 2017, 7.72 hours per generation, and 34% power generation rate in blackout stations; and the average proportion of non-returning batteries in 2017. It is 38%. In August 2017, for example, the power outage accounted for 11.5% of the country, generating 107 thousand times and generating electricity cost of 31 million 20 thousand yuan. The more direct impact is that frequent blackouts, lead-acid batteries lead to serious capacity decay, short cycle life; lead to high investment in batteries, unbearable.

Through exploring the application of cascade batteries, it is found that the cascade batteries have some advantages over lead-acid batteries in terms of cycle life, energy density and high temperature performance, and the performance indexes are superior to lead-acid batteries. Especially, the cycle life of retired lithium iron phosphate battery reaches 2000 times, which fully meets the maintenance environment of frequent blackouts. And cascade batteries have strong environmental adaptability (high temperature resistance). Intelligent ventilation system can be used to replace air conditioning for stations using cascade batteries, which can reduce the cost of maintenance and lay a foundation for subsequent electricity charges.

Yunnan is a pilot province of cascade batteries in China in 2017. A total of 10605 batteries were purchased through the commercial platform, involving the renovation of 2608 stations, totaling 617,000 hours. Taking the Gasha Highway Management Institute of Xishuangbanna Station as an example, the battery capacity calculation method is as follows: battery purchasing price = purchasing unit price * configuration capacity * voltage. The purchasing cost of cascade batteries is 720 yuan lower than that of lead-acid batteries, accounting for about 5.8% of the purchasing price of lead-acid batteries. The service life of lead-acid batteries is 1 year, cascade batteries can reach 3 years, annual consumption cost of lead-acid batteries is 12480 yuan, cascade batteries is 3920 yuan, only 31.4% of the average annual consumption cost of lead-acid batteries.

In terms of maintenance, charging and discharging tests are carried out according to different parameter setting conditions for the use sites of cascade batteries. Combined with the requirements of charging and floating charge settings for each cascade battery manufacturer, comprehensive consideration is given to standardize charging, floating charge, charging current limiting, primary down voltage, secondary down voltage and battery capacity for different cascade battery manufacturers. The requirement of setting parameters can solve the maintenance problem in a large scale.

At the same time, the Yunnan Tower actively communicated with operators to obtain operator support and encourage the tower to carry out battery replacement. Aiming at the problem of battery standby time, a consensus was reached with Yunnan Mobile and a memorandum was signed. The standby time of basic battery support for new tower site and storage station was 3 hours, and the "battery life support service and power generation service exceeding the battery standby time" were settled according to the generation service uniformly.

Cascade batteries as standby equipment, suitable for frequent power outages in Yunnan, Yunnan will continue to expand the use of cascade batteries in 2018. At present, China Tower has issued the enterprise standard for cascade batteries, and has developed the management module for cascade batteries on the operation and maintenance monitoring platform. The "signal dictionary table" also defines the information of cascade batteries separately, and has made great efforts for product standardization, management standardization and performance evaluation digitization. However, as a long-term project, we still need to work together. The same effort.
