【摘要】：城市軌道交通列車具備低能耗、速度快、高環(huán)保等優(yōu)點,是解決城市交通擁擠的有效手段。但由于城市軌道交通系統(tǒng)牽引用電功率波動大,導致了牽引變電站設備容量利用率降低;并且牽引變電站能量流動的單向性使大量再生制動能量被浪費。為了降低能耗、減少運營成本,將儲能技術應用于軌道交通領域已經(jīng)成為國內(nèi)外的研究熱點。儲能系統(tǒng)具備靈活充放電的特點,能平抑功率波動并對再生能量進行循環(huán)利用。利用混合儲能系統(tǒng)的互補特性,在滿足大功率充放電的同時提供能量存儲容量�；谏鲜霰尘�,本文根據(jù)列車實際運行工況、功率數(shù)據(jù),圍繞地面式儲能系統(tǒng)在城軌交通中的容量配置和調(diào)度技術展開了研究。首先,研究了城軌列車的牽引特性和牽引策略。以單輛列車牽引計算為基礎,結(jié)合列車運行的發(fā)車時間間隔,建立了多車牽引功率計算模型,并以此模型模擬牽引變電站的負荷特性。在所建立的模型基礎上進行了牽引計算,得出牽引變電站負荷功率值,從功率、頻率和能量的角度分析了不同發(fā)車時間間隔的牽引負荷特性,為地面式儲能系統(tǒng)的容量配置提供數(shù)據(jù)基礎。其次,針對牽引變電站地面式混合儲能系統(tǒng),采用傅里葉變換和傅里葉反變換的方法來進行功率補償分配。以牽引變電站及地面式混合儲能系統(tǒng)的投資成本最小為優(yōu)化目標,構建牽引變電站混合儲能系統(tǒng)容量優(yōu)化配置計算模型,將功率分配策略融入粒子群算法進行尋優(yōu)求解。然后,針對列車牽引負荷的實時波動,制定了基于低通濾波的實時調(diào)度策略。考慮儲能系統(tǒng)的實際工作狀態(tài),提出了基于儲能荷電狀態(tài)的儲能控制修正策略和過充過放保護策略,提高儲能系統(tǒng)的運行穩(wěn)定性。搭建仿真模型進行策略驗證,結(jié)果表明實時調(diào)度策略可以滿足實時牽引負荷波動需求,并能及時修正實時負荷波動引起的儲能系統(tǒng)調(diào)度計劃偏差,避免儲能系統(tǒng)過充過放。最后,搭建了基于直流微網(wǎng)的城市交通傳動系統(tǒng)試驗平臺的監(jiān)控調(diào)度系統(tǒng)。從物理層到應用層,設計了后臺管理系統(tǒng)數(shù)據(jù)交互接口,開發(fā)了實時監(jiān)控界面。通過平臺的監(jiān)控調(diào)度系統(tǒng)實現(xiàn)了對系統(tǒng)設備的協(xié)調(diào)控制和實時監(jiān)控。
[Abstract]:Urban rail transit trains have the advantages of low energy consumption, high speed, high environmental protection and so on, which is an effective means to solve urban traffic congestion. However, the traction power of urban rail transit system fluctuates greatly. As a result, the capacity utilization ratio of traction substation equipment is reduced, and the unidirectional energy flow of traction substation results in a large amount of regenerative braking energy being wasted. The application of energy storage technology in the field of rail transit has become a research hotspot at home and abroad. The energy storage system has the characteristics of flexible charge and discharge, can suppress the power fluctuation and recycle the regenerative energy, and make use of the complementary characteristics of the hybrid energy storage system. According to the above background, according to the actual operating conditions of the train, the power data, This paper studies the capacity configuration and dispatching technology of ground energy storage system in urban rail transit. Firstly, the traction characteristics and traction strategy of urban rail train are studied. Combined with the departure time interval of train, a multi-vehicle traction power calculation model is established, and the load characteristics of traction substation are simulated by this model. Based on the established model, the traction power of traction substation is calculated and the load power value of traction substation is obtained. The traction load characteristics of different departure time intervals are analyzed in terms of power, frequency and energy, which provide a data basis for the capacity configuration of ground-based energy storage system. Secondly, for the traction substation ground hybrid energy storage system, The methods of Fourier transform and inverse Fourier transform are used to compensate and distribute the power. The optimal objective is to minimize the investment cost of traction substation and ground-based hybrid energy storage system. The optimal configuration model of the hybrid energy storage system in traction substation is constructed, and the power allocation strategy is integrated into the particle swarm optimization algorithm to solve the problem. Then, the real-time fluctuation of train traction load is analyzed. A real-time scheduling strategy based on low-pass filtering is proposed. Considering the actual working state of the energy storage system, an energy storage control correction strategy and an overcharge and over-discharge protection strategy are proposed. The simulation model is built to verify the strategy. The results show that the real-time scheduling strategy can meet the demand of real-time traction load fluctuation and correct the scheduling plan deviation caused by real-time load fluctuation. Finally, the monitoring and dispatching system of urban traffic transmission system test platform based on DC microgrid is built. From the physical layer to the application layer, the data interactive interface of the background management system is designed. The real-time monitoring interface is developed, and the coordinated control and real-time monitoring of the system equipment are realized through the monitoring and dispatching system of the platform.
