本次设计是电力系统规划设计,电力系统规划设计包括电源规划和电网规划两部分.电力系统规划就是根据社会经济发展的需求,能源和负荷的分布,确定合理的电网电压等级、输电方式和网络结构.电源规划是根据电力负荷的发展需要以及电力系统中现有发电厂的供电能力,再经过初步电量平衡计算,确定规定年限内需要增加的发电设备的容量,并选择发电机的型号与台数；同时根据负荷的特点和分布情况,列出几种电源规划方案,进行经济技术比较,选出一个相对合理的方案.电网规划设计是根据输送距离和输送容量确定电压等级,然后选择主变,画出各发电厂与变电所的电气主接线,选择导线并校验,从而得到几种方案,通过经济技术比较选出最佳方案.对所选的方案进行短路电流计算,根据计算结果选择QF和隔离开关.为了验证各变电所是否满足调压要求,必须进行各种运行方式下的潮流计算,得到各支路、节点的潮流分布,再用潮流计算结果算出各节点电压.如果电压不符合要求,调变压器变比和无功补偿,使电压控制在合理范围内.综上所述,本设计满足系统的可靠性、灵活性、经济性等要求.

This design is the electrical power system plan design, the electrical power system plan design plans two parts including the power source plan and the electrical network. The electrical power system plan is acts according to the social economy development the demand, the energy and the load distribution, determines the reasonable electrical network voltage rank, the electric transmission way and the network architecture. The power source plan is needs as well as in the electrical power system according to the power load development the existing power plant power supply ability, again passes through the preliminary electric quantity balance computation, determined stipulated in the fixed number of years needs to increase the generating set capacity, and chooses the generator the model and a number; Simultaneously acts according to the characteristic and the distribution situation which shoulders, lists several kind of power sources plans plan, carries on the economical technical comparison, selects a relatively reasonable plan. The electrical network plan design is according to transports is away from and the transportation capacity definite voltage rank, then chooses the host to change, draws various power plants and the transformer substation electrical host wiring, the choice wire and the verification, thus obtains several kind of plans, selects the preferred plan through the economical technical comparison. To the plan which elects carries on the short-circuit current computation, chooses QF and the isolator according to the computed result. In order to confirm various transformer substations whether satisfies the accent to press the request, must carry on under each movement way the tidal current computation, obtains various legs, the pitch point tidal current distribution, again uses the tidal current computed result to figure out various node voltage. If the voltage does not conform to the requirement, adjusts the transformer to change compared to compensates with the idle work, causes the voltage control in the reasonable scope. In summary, this design satisfies request and so on system reliability, flexibility, efficiency.

This design is an electric power system the programming design, electric power system programming the design include the power supply to program to program with charged barbed wire net two part. the electric power system program to is according to the need, energy that the social economy develop with carry of distribute, certain reasonable of charged barbed wire net electric voltage grade, lose to give or get an electric shock the way with network construction.The power supply programs to is according to the development that the electric power carry the demands and electric power system inside the power supply ability of the current power plant, then pass by first step electricity measure the equilibrium calculation, certain provision the time limit inside need to be increased of generate electricity the equipments's capacity, and combine to choose the model number and set number of the generator;At the same time according to the burthen's characteristics with distribute the circumstance, and list the economic technique comparison of programming project of a few power supplies, proceeding, project that select an opposite reasonable.电网规划设计是根据输送距离和输送容量确定电压等级，然后选择主变，画出各发电厂与变电所的电气主接线，选择导线并校验，从而得到几种方案，通过经济技术比较选出最佳方案。The project to choose to proceeds the short-circuit electric current compute, according to the calculation pan out choose the QF with insulate the switch.为了验证各变电所是否满足调压要求，必须进行各种运行方式下的潮流计算，得到各支路、节点的潮流分布，再用潮流计算结果算出各节点电压。If the electric voltage not agree with to match the request, the 调 transformer change ratio with have no the 功 the repair, make the electric voltage control within the scope of reasonable.综上所述，本设计满足系统的可靠性、灵活性、经济性等要求。
