解釋
湯陰-
Tangyin substation is an important substation which has two transformer of 120mva, eight 220kv lines and three 110kv lines. tangqian line is a 110kv line specially for traction transformer substation. because traction load is high - power nonlinear and asymmetry. it will produce much harmonic and negatvie sequence current, which have done harm to compensation capacitors of tangyin substation. in recent years, the tang6c capacitor often interrupted and in 2001 july the tang7c capacitor ' s discharge pt exploded
湯陰變電站是豫北一座樞紐變電站，有2臺120mva的主變， 8條220kv線路和3條110kv線路，其中的湯牽線是專為牽引變電站供電的110kv線路。由於電力機車屬于大功率的非線性負荷，且三相不對稱，在其運行過程中必然會產生較大的高次諧波和負序電流。 -
Convenient and fast transportaion is tangyin famous character. crossing tangyin, jingguang railway, tanghe railway and tangtai railway make tangyin an important railway transportation pivot. jingzhou express high way, 107 national highway, hu - tai line and tang - shang line intersect the county town. roads radiate from tangyin in every directions. it is only one hours ride from tangyin to xinzheng and handan lnternational airports
京廣鐵路與湯鶴支線和湯臺地方鐵路連接南北西東，使湯陰成為豫北地區重要的鐵路運輸樞紐.京珠高速公路、 107國道、壺臺公路、湯上公路在境內縱橫交錯，五鄉五鎮村村公路暢通.湯陰南至新鄭國際機場、北到邯鄲國際機場，只有一個多小時的路程。 -
Because the harmonics in tangyin substation are primarily from electric traction loads, this paper gives the structures of several main locomotive models and general harmonics they produce. the harmonics produced by electric locomotive have a characteristic that their range and phase are both dispersive. this paper also analyzes the impedance - matching balance transformer ' s structure and harmonics injected into the power system at its primary side, and sums up the characteristics of the harmonics from electric traction loads in the tangyin traction substation
鑒于湯陰變電站的諧波主要來自電力牽引負荷，本文列舉了電力機車幾種主要車型的結構以及它們產生諧波的概況，得出了電力機車的各次諧波電流幅值和相角具有較大分散性的特點。針對湯陰牽引變電站的牽引變壓器，分析了阻抗匹配平衡變壓器的結構及其高壓側注入電網的諧波，推導了有關計算公式。通過理論分析並結合湯牽線的實測諧波數據，歸納了電力牽引負荷注入湯陰變電站的諧波的特點。 -
Firstly, this paper gives the main harmonic sources and their harms to power systems, and then lists some technique methods now used to handle harmonics. this paper takes tangyin substation as the study object
本文首先介紹了目前電力系統中存在的主要諧波源及其對電力系統的危害，並列出了治理諧波的一些主要技術措施和對這些措施評價。
