【摘要】：長期以來，我國的電力規(guī)劃研究工作重心主要放在電源規(guī)劃和主網(wǎng)規(guī)劃上，我國配電網(wǎng)建設(shè)相對落后，缺乏合理的規(guī)劃設(shè)計，設(shè)備也較陳舊。近年來，國家電力部門已經(jīng)越來越清楚地意識到配電網(wǎng)規(guī)劃改造的必要性，并開始把電力規(guī)劃的重心擺在了中低壓配電網(wǎng)的規(guī)劃改造上。各地區(qū)也紛紛從現(xiàn)有的配電網(wǎng)狀況進行分析，根據(jù)實際需要和可能性進行再規(guī)劃和改造，以望提高供電的安全性、可靠性、經(jīng)濟性以及電能質(zhì)量，從而適應當前國民經(jīng)濟和社會的需要。 隨著國民經(jīng)濟及人民生活對電力需求的不斷增長,目前佛山市的電力網(wǎng)絡已難以滿足負荷日益增長的需求。部分線路環(huán)網(wǎng)點設(shè)置過多且難以有效的起到備用的作用（比如季華站汾江南線與8回其他線路有環(huán)網(wǎng)點），運行方式的多樣性增加了配網(wǎng)運行的復雜程度。為保證今后城市經(jīng)濟的持續(xù)發(fā)展，配電的規(guī)劃、建設(shè)與改造工作越來越舉足輕重地擺在各級決策者面前。在城市中壓配電網(wǎng)規(guī)劃中，網(wǎng)架結(jié)構(gòu)的選取顯得尤為重要。因此，在對現(xiàn)有電網(wǎng)的可轉(zhuǎn)供電能力提升改造的過程中，迫切需要一種能結(jié)合電網(wǎng)現(xiàn)狀、便于過度、接線清晰、操作簡單的接線模式來指導，又好又快又省的提高配網(wǎng)管理水平。 本論文先是介紹了配電網(wǎng)重構(gòu)及目標網(wǎng)架實施的目的與意義，分析了國內(nèi)外研究的現(xiàn)狀；結(jié)合“十二五”期間電網(wǎng)建設(shè)及2014年佛山市禪城區(qū)中低壓配電網(wǎng)年度規(guī)劃，對禪城區(qū)配電網(wǎng)絡現(xiàn)狀進行梳理，介紹了禪城區(qū)配電網(wǎng)現(xiàn)狀，包括供電區(qū)域、上級電源和10kV線路等情況，分析了禪城區(qū)配電網(wǎng)存在的主要問題，包括供電能力、網(wǎng)絡結(jié)構(gòu)、運行水平和建設(shè)環(huán)境，研究了禪城區(qū)配電網(wǎng)規(guī)劃的基本思路，包括10kV電力電纜和10kV電力架空線的網(wǎng)絡結(jié)構(gòu)及接線方式；分析了配電網(wǎng)絡重構(gòu)的一些算法，提出了基于單親遺傳算法的配網(wǎng)重構(gòu)模型，用配電網(wǎng)可靠性測試系統(tǒng)IEEE-RBTS Bus4為算例，在算出原配電網(wǎng)絡的可靠性后，通過優(yōu)化改變該網(wǎng)絡結(jié)構(gòu)，提高該系統(tǒng)的可靠性，同時也驗證了算法的合理性；利用基于可靠性的中壓配電網(wǎng)網(wǎng)絡優(yōu)化算法，結(jié)合禪城區(qū)中壓配電網(wǎng)線路規(guī)劃的基本思路和網(wǎng)絡接線結(jié)構(gòu)的典型接線方式要求，采用了優(yōu)化網(wǎng)絡接線、改變現(xiàn)狀網(wǎng)絡的薄弱環(huán)節(jié)等多種方法研究了佛山禪城地區(qū)配電網(wǎng)目標網(wǎng)架實施策略。結(jié)合現(xiàn)有電網(wǎng)的聯(lián)絡關(guān)系，，以佛山供電局典型接線方式為指導、研究了2～3種典型接線的衍生接線模式來指導配網(wǎng)改造，并從配電網(wǎng)網(wǎng)架規(guī)劃設(shè)計考慮，提出了五種建議方式及解決措施：1）配網(wǎng)網(wǎng)架結(jié)構(gòu)由不超過4條饋線的饋線組來實施分區(qū)供電；2）饋線組從五種典型接線方式中選取，其中電纜線路首選兩供一備；3）接線模式由“單放射”過渡到“兩分段兩聯(lián)絡”；4）明確線路干支線，合理設(shè)置環(huán)網(wǎng)點和開關(guān)房，并避免分支環(huán)網(wǎng)；5）向符合典型接線的配網(wǎng)逐步推廣“兩遙+故障指示器/饋線自動化”。
[Abstract]:For a long time, the focus of China's power planning research work is mainly on power planning and main network planning. The construction of distribution network in China is relatively backward, lack of reasonable planning and design, and the equipment is obsolete. In recent years, the national electric power department has become more and more aware of the necessity of distribution network planning and transformation, and began to plan the power of electricity. The center of gravity is placed on the planning and transformation of the medium and low voltage distribution network. Each area has also been analyzed from the existing distribution network, and replanned and reformed according to the actual needs and possibilities, in order to improve the safety, reliability, economy and power quality of the power supply, so as to meet the needs of the former national economy and the society.
With the increasing demand for electricity in the national economy and people's life, the power network in Foshan has been difficult to meet the increasing demand of the load. In order to ensure the continuous development of the urban economy in the future, the planning, construction and transformation of distribution are becoming more and more important to the decision-makers at all levels. In the planning of the urban medium voltage distribution network, the selection of the structure of the grid is particularly important. Therefore, the transformation of the power supply capacity of the existing power grid is improved. In the process, there is an urgent need to guide the connection mode which can be combined with the current situation of the power grid, which is convenient for excessive, clear wiring and simple operation, and improves the management level of the distribution network quickly and quickly.
This paper first introduces the purpose and significance of the distribution network reconfiguration and the implementation of the target network frame, analyzes the status of the research at home and abroad, and combs the current situation of the distribution network in Chancheng District in conjunction with the power grid construction in 12th Five-Year and the annual planning of the middle and low voltage distribution network in Chancheng District of Foshan in 2014, and introduces the current status of the distribution network in Chancheng, including the current status of the distribution network, including the current situation of the distribution network in Chancheng. The main problems existing in Chancheng distribution network are analyzed, including power supply, power supply and 10kV line, including power supply capacity, network structure, operation level and construction environment. The basic ideas of distribution network planning in Chancheng area are studied, including network structure and connection mode of 10kV power cable and 10kV power frame, and distribution network is analyzed. Some algorithms of collaterals reconfiguration are proposed based on the single parent genetic algorithm (PGA). The reliability test system IEEE-RBTS Bus4 is used as an example. After calculating the reliability of the original distribution network, the reliability of the system is improved by optimizing the network structure, and the rationality of the algorithm is verified at the same time; and the reliability based on reliability is also used. The network optimization algorithm for medium voltage distribution network, combined with the basic train of thought of the middle voltage distribution network planning in Chancheng district and the typical connection mode of network connection structure, has studied the implementation strategy of the target network framework of the grid distribution network in Foshan Chancheng area by optimizing the network connection and changing the weak link of the current network. It combines the existing grid with the existing grid. With the guidance of the typical connection mode of Foshan Power Supply Bureau, the derivative wiring modes of 2~3 typical connections are studied to guide the transformation of the distribution network, and five suggestions and solutions are put forward from the layout and design of the distribution network. 1) the distribution network structure of the distribution network is supplied by a feeder group of no more than 4 feeder lines; 2) The feeder group is selected from five typical wiring modes, of which the first choice of cable lines is two for the first choice; 3) the connection mode is transferred from "single radiation" to "two segment two liaison"; 4) clear line trunk line, reasonable setting ring network and switch room, and avoiding branch ring network; 5) gradually popularize "two remote + failure" to the typical connection network. Indicator / feeder automation.
