压气站布置的基本步骤The basic steps of compressor station layout 根据上面讨论，归纳出压气站布置的基本步骤如下According to the above discussion, the basic steps of compressor station layout are summarized as follows： （1）根据末段储气要求确定末端参数：P1max、P2min、和lZ；The terminal parameters were determined according to the requirements of the terminal gas storage: P1max, P2min, and lZ （2）根据任务流量和式（10-8）、（10-9）或（10-6）初步确定压气站数，并化整（向上）；According to equation (10-8), (10-9) or (10-6) of task flow sum, the number of compressor stations is preliminarily determined and integrated (up). （3）由于站数化整，需根据式（10-10）至（10-16）复核最大工作压力Pmax下的最大流量Qmax（或QZmax），或者根据任务流量Q核算该流量下的最高工作压力PmaxDue to the integration of stations, the maximum flow Qmax (or QZmax) under the maximum working pressure Pmax should be checked according to formula (10-10) to (10-16), or the maximum working pressure Pmax under the maximum working pressure should be calculated according to the task flow Q （4）根据式（10-3）或（10-5）计算各站间的站间距，并布置压气站According to formula (10-3) or (10-5), calculate the station spacing between each station and arrange the compressor station； （5）计算各站其余的工艺参数：如进站压力PZi、压力比ε、压头H、功率N和出站温度T2等等。The remaining process parameters of each station are calculated, such as inlet pressure PZi, pressure ratio, head H, power N and outbound temperature T2, etc. （6）根据计算成果和实际需要对某些站进行调整，并重新核算。According to the calculation results and actual needs for some stations to adjust, and re - accounting.
根据经验（例如，站间距约为110~150km）初步确定压气站数和布置其余站的位置。这样就等于初步确定全部站址，已知各站的站间距。结果，“预先固定某些站址的压气站布置”就转化为一个工艺核算——调整——再核算的问题。其步骤如下Under the above known conditions, the number of compressor stations and the locations of other stations are determined preliminarily according to experience (for example, the station spacing is about 110~150km). This is equal to the preliminary determination of all stations, known the station spacing. As a result, "pre-fixed compressor station layout of some sites" is transformed into a process accounting - adjustment - re-accounting problem.（）
A、根据经验确定全部压气站的站址和站间距。作出全线布置草图，图上表明各种站场的位置、站间距、各段输气量、各处的进气量和分气量，以及已知的各点压力等According to experience determine all compressor station site and station spacing. Make a sketch of the layout of the whole line, showing the position of various stations, the distance between stations, the volume of gas transmission in each section, the volume of air intake and distribution in each place, and the known pressure at each point
B、根据已知的流量和各站出站的最高压力Pmax，进行各段、各站间的水力、热力计算，得出各站的进站压力PZi+1和各进气点、分气点的压力According to the known flow rate and the highest pressure Pmax of each station, hydraulic and thermal calculation was carried out for each section and station, and the inlet pressure PZi+1 of each station and the pressure of each inlet point and air distribution point were obtained
C、计算各压气站工况，求出各站的出站温度T2，压头H和功率NCalculate the working conditions of each compressor station, and figure out the outbound temperature T2, pressure head H and power N of each station
D、根据各站的变转速特性确定各站的调节方案According to the variable speed characteristic of each station, the adjustment scheme of each station is determined
E、检查各站间和各站的工作参数是否符合要求和合理。Check whether the working parameters of each station and each station are in accordance with the requirements and reasonable
A . 地理位置上直接相邻的小区一般要作为邻区
B . 邻区一般都要求互为邻区，在一些特殊场合，可能要求配置单向邻区;
C . 对于密集城区和普通城区，由于站间距比较近，邻区应该多做;实际网络中，既要求配置必要的邻区，又要避免过多的邻区。
D . 对于市郊和郊县的基站，虽然站间距很大，但一定要把位置上相邻的作为邻区，保证能够及时切换，避免掉话
E . 因为WCDMA的邻区不存在先后顺序的问题，而且检测周期比较短(一般32个同频邻区只需要320ms的测量周期)，所以只需要考虑不遗漏邻区，而不需要严格按照信号强度来排序相邻小区
