随着我国中、小型水电站的更新改造和大、巨型水电机组的研制、投产，对机组的稳定、可靠和经济运行等提出了更高的要求，必须研究先进、可靠的水轮机微机调速器。各种新型控制策略的应用，使调速器的性能不断改善。电液转换器是调速器电、液信号转换的关键元件，要求其必须具有很高程度的可靠性。大、巨型机组在电力系统中起着举足轻重的作用，必须采用各种先进技术以保证其可靠性和稳定性。负荷扰动是引起系统不稳的主要原因，必须采取有效的抗扰动方法。PID调节律仍是主要的调节律。因各种新的控制技术目前还存在着局限性，且各水电站又具有很强的个性。因此，将各种新型控制策略广泛用于实际水电机组控制仍有一些困难。

Along with the renew and rebuilt of middle and small hydro-powerstations and the development and manu-facture of large and giant hydro-power unit, there are higher and higher requirements for stability, reliabilityand economical operation of the unit, and thus, it is necessary to conduct study of advanced and reliable com-puter run turbine actuator governor. Application of various advanced controlling strategies promotes the im-provement of actuator governor characteristics. Being the key element for transferring between the electric andliquid signals in the actuator governor, the change-over switch must be highly reliable. Because of its decisiveimportance in electric system, the reliability and stability of large and giant power generation units must be en-sured by applying possible advanced techniques. Load disturbance is the main reason causing unstable situationin the system, therefore, effective anti-disturbance ways should be used. PID regulation law is still the majorregulation law. Because there are limitations presently existing in the new controlling techniques and evidentspecific features for different hydro-power stations, there are some difficulties in widely applying all the newcontrolling strategies in actual hydro-power units.
