Title: Frequency stabilization
Inventor: TAKAHASHI TAKAHIRO
IPC: H02J3/24
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To maintain frequency within the stable operating area of a generator by calculating maximum transient frequency at the time of disconnecting a system from obtained characteristics, and controlling frequency within the stable operating area of the generator. SOLUTION: A central processing unit 32 fetches measured system frequency, calculates the variation of frequency with respect to reference frequency, and discriminates whether or not an accident to be controlled occurs is a power system. If there are no accidents in the power system, the measured tidal current value and the operating data of generators 11, 12 collected from a central power feed command station 31 are fetched to calculate the maximum and minimum frequency for an assumed accident and a destined frequency.  It is discriminated from the calculated frequency results whether or not the destined frequency and the maximum and minimum frequency are within the stable operating area of a generator, and if not, frequency calculation and discrimination are conducted repeatedly until the destoned frequency and the maximum and minimum frequency have reached a condition which is within the stable operating area of a generator.

Title: Thermal accumulation device
Inventor: YAMASHITA KAZUO
IPC: F28D20/02
Filed: 1984-12-04
Abstract: PURPOSE:To restrict a temperature increasing at the small bag portions, make a low range of distribution of temperature and provide a uniform distribution of it by a method wherein the small bag portions where the temperature of the mat is increased are not provided with a heater in opposing to them or the density of the heater is made low. CONSTITUTION:Since the central part of a mat 4 has portions where the density of the heater is low, the central part shows a slower increasing in temperature than that of the surrounding small bags 3 due to an accumulated heat of the latent heat of the thermal accumulation material less than the melting point thereof, and its temperature is increased relatively fast and reached to its melting point. However, at the melting point, the surrounding small bags 3 have latent heat and accumulated heat, so that an entire mat 4 shows the same temperature. At this time, almost of all the latent heat and accumulated heat are carried out, the latent heat and the accumulated heat around the small bags are finished and when the temperature is increased, the surrounding heat is absorbed, resulting in performing the latent heat and accumulation of heat. Therefore, the portions 12 having less density of heat. Therefore, the portions 12 having less density of heaters show a slower increasing in temperature than that of the surrounding state.
