To add " there are many loopholes in the operation and sales practices of telecommunications service providers, " after " that, as " ; to add " and such complaints from the public are often not followed up effectively by government departments, " after " in recent years, " ; to add " stipulate corresponding penalties " after " to cover pay television, " ; and to add " ; furthermore, as the hong kong housing authority has signed agreements with pay television operators, these operators can enter the buildings to set up and maintain communal aerial systems and can deploy front - line promoters to approach the residents to sell other various commercial services, using the provision of exclusive maintenance and supply services as a selling point and adopting unscrupulous means to entice or mislead the residents into signing an agreement with them, causing great disturbance to the residents ; in this connection, the government must adopt measures to combat such sales malpractices, take the initiative to inform public rental housing tenants of the rights and responsibilities of the operators and, when the operators resort to malpractices or malpractices are reported by residents, take immediate action to investigate the matter and issue warning to and penalize the operators concerned ; the government must also review the problem of inequity in accessing system information by consumers and the telecommunications service providers, whereby consumers have no means or right to obtain true and accurate information about the systems that they are using and can only pay the fees according to the volume, system and time slots of their calls shown on the records provided unilaterally by the service providers, and in case of queries about such information, the decision of the service providers prevails and there is no channel for the consumers to dispute or verify ; to this end, the government should expeditiously study how to ensure that consumers have the rights to know, choose, verify, appeal and claim for compensation in the provision of telecommunications services including pay television, local and cross - boundary telecommunications and internet services " after " in the contracts "
在"鑒于"之後加上"各電訊服務提供者的營運和銷售存在不少漏洞, "在"不斷增加, "之後加上"而市民的投訴又往往得不到政府部門的有效跟進處理, "在"收費電視, "之後加上"訂定相應的罰則, "及在"標準合約條款"之後加上"此外,由於香港房屋委員會與收費電視營辦商簽訂協議,該等營辦商可進入大廈鋪設及維修公共天線系統,並調派前線銷售人員,以獨家提供維修及供應服務作為招徠,向住戶推銷其他各種商業服務,以不當手法誘使或誤導住戶與他們簽約,對居民造成很大困擾就此,政府必須採取措施打擊上述違規營銷的手法,並主動告知公屋住戶該等營辦商的權責范圍,遇有營辦商作出違規的行為或居民舉報營辦商的違規行為時,須立即追查,並向有關營辦商發出警告及作出處分政府亦須檢討現時消費者與電訊服務供應商所獲系統資訊並不對等的問題,即消費者無從及無權得知他們所選用系統的真實資料,令他們只能按服務供應商單方面提供有關通話量通話系統及通話時段的記錄繳交費用,遇有消費者質疑上述資料時,往往只由服務供應商作最終決定,消費者無從申辯或查證就此,本會促請政府盡快研究如何就各類電訊服務包括收費電視本地及跨境電訊網際網路等的提供,確保消費者享有知情權選擇權覆核權投訴權及索償權" 。Secondly, to achieve the independent regulation of active and reactive power output from the generator side which is designed for the purpose of tracing the maximum wind - energy capturing. the paper has analyzed the mathematic model of the ac excited doubly - fed machine and the stator field orientation control strategy of the motor as vscf wind power generator. thirdly, it has put forward and designed the dual pwm converter with the capacity of energy flowing bidirectional aimed at the demand of rotor energy bidirectional flow. the author constructed reliable and integrated experimental system and did a series of experimental study including no - load, cutting - in network and power generation at, below and above the synchronous speed
論文首先分析了風機運行特性及其最佳風能利用原理,通過模擬及實驗驗證了採用直流電機的輸出特性模擬風力機的最大輸出功率曲線的可行性,並給出了模擬系統的硬體結構;然後為了實現交流勵磁發電機有功、無功功率獨立調節機理,分析了交流勵磁雙饋發電機的數學模型和在追蹤最大風能捕獲變速恆頻風力發電時必需的定子磁鏈定向矢量控制策略;針對雙饋發電機轉子能量雙向流動的要求,提出並設計了具有能量雙向流動能力的雙pwm交流勵磁用變頻器;最後為實現從理論到實踐的全面研究,研製出了一套小功率完整的雙pwm變頻器交流勵磁的雙饋風力發電機實驗系統,進行了空載、並網、同步速及上、下的發電運行等一系列的運行實驗;所完成的模擬和實驗研究均驗證了理論、模型和控制策略的正確性、可行性。The reactive power optimization compensation is to find the suitable compensation place and the best compensation capacitance by adjusting the generator bus voltages, transform taps and reactive compensation capacities in the condition of satisfying power load requirement, which can guarantee the secure and high quality power for consumers. the improved genetic algorithm is applied in this thesis according to the features of reactive power optimization of high voltage transmission bus, which are the non - linear problems with multi - variables and multi - restrictions
電網無功優化補償是在有功潮流調度給定的情況下,以負荷節點電壓和線路輸送無功功率作為狀態變量,運用優化演算法,調節發電機節點電壓、變壓器可調分接頭和無功補償裝置,在滿足電力負荷的要求下,尋求合理的無功補償點和最佳補償容量,保證電網能夠安全、優質地向用戶供電。The result is that today ' s broadband duopoly between the fixed - line telecoms operators and the cable companies is now moving into the wireless sector
結果是,固定電話服務商與有線電視服務商結成的壟斷寬帶接入的寡頭聯盟把目光都開始轉向無線網路運營上。Wireless features : network directed system selection
無線電通信特徵:網路定向系統選擇Consumers successively plunged a large number of silicon controlled commuted devices ( such as steel rolling 、 electrized locomotive 、 aluminium electrolysed devices etc ) and smelting devices to improve their produced efficiency or to save energy. on the one hand it is good for consumers, on the other hand it will arouse the fluctuation of voltage and frequency and it will result in the collision of the active and reactance capacity. meanwhile these nonlinear loads bring much harmonic into the electric network which deteriorate the quality of power supply and hazard the online device enormously
用電部門為了提高生產效益、節約能源,在大電網中相繼出現了大量的可控硅整流裝置(如軋鋼、電氣化機車、鋁加工電解設備等)以及冶煉設備,這些設備的投入使用對節能有一定好處,但給電網造成有、無功沖擊,引起電壓和頻率的波動,同時,這些非線性負荷向電網注入大量諧波,大大惡化了供電系統的電能質量,給用電設備帶來了極大的危害。分享友人
