【摘要】：開(kāi)發(fā)新能源是解決能源危機(jī)與環(huán)境污染的一項(xiàng)重大舉措。風(fēng)光儲(chǔ)互補(bǔ)系統(tǒng)充分利用風(fēng)、光資源在時(shí)間、空間上的互補(bǔ)性，加上儲(chǔ)能裝置的能量調(diào)節(jié)作用，能輸出較平穩(wěn)功率，增加了電網(wǎng)對(duì)風(fēng)、光資源的接納程度。本文主要研究互補(bǔ)系統(tǒng)建設(shè)規(guī)劃階段的容量?jī)?yōu)化配置方法和運(yùn)行階段的短路電流特性及對(duì)聯(lián)絡(luò)線繼電保護(hù)的影響兩方面。 首先，本文在研究風(fēng)光儲(chǔ)互補(bǔ)系統(tǒng)原理、結(jié)構(gòu)、運(yùn)行方式的基礎(chǔ)上，建立了以抽水蓄能電站為儲(chǔ)能裝置、工程壽命內(nèi)總收益最大為目標(biāo)函數(shù)、風(fēng)光資源互補(bǔ)性、風(fēng)光資源利用率、輸出跟蹤負(fù)荷曲線等為約束條件的大規(guī)模互補(bǔ)發(fā)電系統(tǒng)容量?jī)?yōu)化配置模型，并提出了一種變步長(zhǎng)循環(huán)離散求解算法。 其次，在建立了雙饋式風(fēng)力發(fā)電機(jī)組、光伏發(fā)電系統(tǒng)、抽水蓄能機(jī)組的暫態(tài)模型基礎(chǔ)上，建立了交流母線組網(wǎng)型互補(bǔ)發(fā)電系統(tǒng)的PSCAD暫態(tài)仿真模型。并通過(guò)研究風(fēng)速、光強(qiáng)等環(huán)境因素變化時(shí)的互補(bǔ)系統(tǒng)輸出特性，驗(yàn)證了仿真模型的正確性。 最后，，基于風(fēng)光儲(chǔ)互補(bǔ)系統(tǒng)的PSCAD暫態(tài)仿真模型，研究了最優(yōu)容量配置下互補(bǔ)發(fā)電系統(tǒng)三相短路、單相接地、兩相接地、兩相短路時(shí)的短路電流特性，詳細(xì)分析了風(fēng)速、光強(qiáng)、抽水蓄能機(jī)組運(yùn)行狀態(tài)、撬棒保護(hù)動(dòng)作狀態(tài)以及風(fēng)、光、儲(chǔ)容量配比對(duì)三相短路電流特性的影響。 論文對(duì)比分析了互補(bǔ)發(fā)電系統(tǒng)與常規(guī)電源短路電流特性的差異，并在此基礎(chǔ)上研究了互補(bǔ)系統(tǒng)并網(wǎng)后對(duì)聯(lián)絡(luò)線上三段式零序電流保護(hù)、三段式相間距離保護(hù)的影響。 論文研究成果對(duì)風(fēng)光儲(chǔ)互補(bǔ)系統(tǒng)的設(shè)計(jì)和安全穩(wěn)定運(yùn)行具有指導(dǎo)意義和實(shí)用價(jià)值。 本文工作得到國(guó)家高技術(shù)研究發(fā)展計(jì)劃（863計(jì)劃）重大項(xiàng)目《高滲透率間歇性能源的區(qū)域電網(wǎng)關(guān)鍵技術(shù)研究和示范》（2011AA05A105）的資助。
[Abstract]:The development of new energy is an important measure to solve the energy crisis and environmental pollution. The complementary system makes full use of wind and light resources in time and space together with the energy regulation of energy storage device to output more stable power and increase the acceptance of wind and light resources in the power grid. In this paper, the optimal configuration of capacity in the construction planning phase of complementary system and the short-circuit current characteristics in the operation phase and the influence on the relay protection of the tie-line are studied in this paper. First of all, on the basis of studying the principle, structure and operation mode of the wind and storage complementary system, this paper establishes a pumped-storage power station as the energy storage device, the maximum total income in the project life as the objective function, and the complementarity of the scenery and resources. A capacity optimization model for large-scale complementary generation systems with constraints such as wind resource utilization and output tracking load curves is proposed. A variable step size cyclic discrete solution algorithm is proposed. Secondly, on the basis of the transient model of doubly-fed wind turbine, photovoltaic system and pumped storage unit, the PSCAD transient simulation model of AC busbar netted complementary generation system is established. The correctness of the simulation model is verified by studying the output characteristics of the complementary system when the environmental factors such as wind speed and light intensity change. Finally, based on the PSCAD transient simulation model of wind-storage complementary system, the short-circuit current characteristics of the complementary generation system with three-phase short circuit, single-phase earthing and two-phase short circuit under the optimal capacity configuration are studied, and the wind speed and light intensity are analyzed in detail. The effects of the operation state of pumped storage unit, the operation state of crowbar protection and the ratio of wind, light and storage capacity on the characteristics of three-phase short-circuit current. In this paper, the difference of short circuit current characteristics between complementary generation system and conventional power supply is analyzed, and the influence of complementary system on three-segment zero-sequence current protection and three-segment inter-phase distance protection on tie line is studied. The research results of this paper are of guiding significance and practical value for the design and safe and stable operation of the complementary system of scenery storage and storage.
