【摘要】 电力系统稳定是电网安全运行的关键,一旦遭到破坏,必将造成巨大的经济损失和灾难性的后果,世界各国不乏惨痛教训之例。近年来随着我国电力事业的飞速发展,网架结构日趋庞大,大型弱联系的电力系统形成及呈现负阻尼效应的快速自动电压励磁调节装置的大量普及使用,对电力系统稳定装置的需要日益迫切。 本论文以多变量数字式电力系统稳定装置的设计为主要内容。文中首先介绍了电力系统稳定器的原理及其基本的理论依据,然后着重介绍了多变量数字式电力系统稳定装置的软、硬件实现。其中,该电力系统稳定器的主芯片采用了TI公司的TMS320F2812定点DSP芯片,该芯片具有32位中央处理器,主频达到150MHZ,从而保证了整个系统具有较强的数值运算能力,为各种数字信号处理算法提供了强有力的硬件支持。同时,该电力系统稳定器的所有功能均通过软件实现,采用了C语言和DSP汇编语言混合编程的方法,这既保证了软件具有C语言结构清晰易读、开发周期短的特点,同时又使整个软件具有较高的效率。本文论及的多变量数字式电力系统稳定装置,可适应不同的现场条件和要求,组态灵活、方便,可以满足多种电力系统稳定方案的实施需求。更多还原

【Abstract】 Power system stability plays an important role in the safe operation of network, which will cause enormous economic losses and calamitous consequence when it is destroyed. There have been lots of bitter lessons existed in the world. In recent years, along with the development of the electric undertaking of our county, the expanding of the power system grid structure ,the forming of the power system of the large-scale weak connection,and the popularization of the fast automatic voltage excitation regulator which takes on the negative damping effect, the requirements for power system stabilizers (PSS )are urgent day by day.This paper focuses on the resarch and development of the multivariable digital power system stabilizers.In the paper we introduced the origination of the power system stability and its principle mathematic analysis method firstly. Then the design of software and hardware on the power system stabilizers is illuminated in detail.During the design of the PSS, a high performance chip,DSP(digital signal processor) is adopted, whose type is TMS320F2812. This device is 32 bit fixed-point digital signal processor,works in 150MHZ.This ensures that the system has the high numberic operation capability,and the processor also supports all kinds of digital signal processing algorithms.At the same time,the program realizes all the PSS functions.And the software is programed with C and assembler language,whitch ensures that the software has clear structure and the short development cycle,at the sametime,the hign efficiency can be obtained. Moreover, the multivariable digital power system stabilizers can adopt the different conditions and requirements, the configuration is flexible, convenient,that can meet the demand of many kinds of power system.更多还原
